AION 2 vs Throne and Liberty: Which NCSoft MMORPG to Play

Both are free-to-play MMORPGs from NCSoft, and the honest answer is that they are asking for different things. AION 2 is wings, aerial combat and a permanent two-faction war in a service that opened to everyone on October 5, 2026. Throne and Liberty is a ground-bound, guild-first MMO that launched on September 17, 2024, already ships castle sieges and two years of content, and runs on consoles as well as PC. Install AION 2 if you want to fight in the sky; install Throne and Liberty if you want to fight over a castle with 70 guildmates.

Verified October 10, 2026. AION 2 dates, platform and launch-day figures come from NC’s own newsroom release of October 6, 2026 and the Steam store listing. Throne and Liberty dates, currencies and passes come from the Amazon Games business model notice and the official Throne and Liberty site. Third-party player trackers are named in the line where they appear, and every number that comes from one is labelled.

Which NCSoft MMORPG should you play?

Default answer: AION 2 if flight and faction war are the point, Throne and Liberty if guild politics, mature content and console play are the point. Both are free, neither costs anything to try, and neither purchase decision is irreversible — so the useful question is which one matches what you want from an MMO this month, not which one wins a score.

Two practical notes on that table. First, the AION 2 rows describe the global service only: the Korea and Taiwan build has been live since November 19, 2025 with its own clients and no account overlap, which the global versus KR/TW comparison explains in full. Second, the Throne and Liberty rows describe the game as its Western publisher has documented it — and that publisher is changing, a point developed below.

How does combat and travel differ between the two?

AION 2 makes the sky part of the fight; Throne and Liberty keeps you on the ground and gives you transformations to cross it quickly. NC’s launch-day copy describes AION 2 as “built on freedom of movement and flight”, promising a “best-in-class flying experience packed with spectacular aerial combat and environmental traversal”, and says the combat “blends precision, timing, and positioning with a traditional tab-targeting offering”. Flight is not a taxi service in AION 2 — it is where the combat happens.

Throne and Liberty takes the opposite route. Its combat is ground-based with two camera styles — a classic tab-target setup and an action-style option — and its movement system is morphs rather than mounts. There are no rides in the traditional sense: you transform into creatures for three jobs, dashing across land, gliding off a height, and swimming. You can coast a long way from a cliff edge, and you cannot simply take off and hold altitude the way an AION 2 character with wings can.

If you have played the original AION and missed the feeling of a fight that opens by diving out of the sky, that is the clearest separator. The gameplay overview covers what AION 2 confirmed about its world size and content, and the review page records what the September Launch Scale Test actually showed about how the flight combat feels in hands.

Do you pick a class, or do your weapons pick for you?

AION 2 gives you eight classes and no way to mix them; Throne and Liberty gives you no classes at all and lets two weapons define everything. This is the single biggest structural difference, and it decides how much time you will spend in a character creator before you ever swing a weapon.

AION 2 launches globally with eight classes — Gladiator, Templar, Assassin, Ranger, Sorcerer, Spiritmaster, Cleric and Chanter — and every one of them is open to both factions, so neither your tank nor your healer is decided by the side you picked. The classes overview lists them by role, and the faction choice page explains why the class question and the faction question should be settled separately.

Throne and Liberty deletes the picker. You equip two weapons, swap between them whenever you like, and your skills, masteries and playstyle follow from that pair rather than from a class label. Two players running the same “class” in the usual MMO sense can end up with completely different rotations, and swapping a weapon pair is a build change rather than a new character.

What is the PvP actually about?

AION 2’s PvP is a two-sided war between factions you cannot leave; Throne and Liberty’s is a political economy run by guilds, where owning the castle changes what everyone pays in the auction house. Both are large-scale and open-world, but they organise players completely differently.

AION 2 sorts every character into Elyos or Asmodians at creation and fights that out in the Abyss, alongside rifts that let one side invade the other and instanced arena and battlefield modes. The pvp page separates what NCSOFT has named from what is still unannounced, and the faction pick itself is permanent for that character — no faction change service exists.

Throne and Liberty has no factions. It has guilds, and guilds fight over a castle, over open-world field bosses, and over the tax delivery event that moves the castle’s earnings through the map. The structural hook is unusually concrete: the guild that owns the castle sets an extra tax rate on auction-house trades, within a band, and that tax is paid out to the guilds that win the siege and tax events in Lucent. Politics in Throne and Liberty is not flavour text; it is a currency distribution mechanism.

How does each game charge you money?

Both are free, but they put the paywall in different places: AION 2 gates access to the player economy behind an optional membership, while Throne and Liberty keeps its auction house open and lets you earn the premium currency inside it. Neither game has a box price.

The contrast that matters is the auction house. In Throne and Liberty every trade is priced in Lucent, Lucent can be bought with real money or earned by playing, and only base, un-enhanced gear that did not drop in instanced content can be listed — so the paid route buys convenience and cosmetics rather than finished gear. In AION 2 the Market and the Kina-Quna exchange are the membership benefits that the pay-to-win argument turns on, because a bridge from real money into the earned currency changes what a card payment can become.

That whole argument has its own page — the pay-to-win and free-to-play guide works through it layer by layer, and the free-to-play explainer itemises what a free account actually reaches. Nothing on this page needs you to spend anything before you have decided which game you prefer.

Where can you play them, and how old is each?

Throne and Liberty is the more portable and the more mature of the two; AION 2 is the newer and, for now, the more restricted. Platform is the one row of this comparison that no patch is likely to change soon.

That last row is worth stopping on. NC announced on August 12, 2026 that it would take Throne and Liberty’s global publishing back from Amazon Game Studios, and the Western service moves to NC — through FirstSpark Games — with a character and item carrying maintenance on November 10, 2026. Your Throne and Liberty account survives that move, but the operator you send feedback to is changing while AION 2 is being operated by NC directly with no intermediary at all.

Dates and windows for the AION 2 side live on the release date and launch time page, and the server list and regions guide covers how the global worlds are laid out.

How healthy is each population right now?

AION 2 is the busier game on Steam by a wide margin, and Throne and Liberty’s Steam population has settled far below its 2024 peak. Read both figures as Steam-only: AION 2 also runs on PURPLE, and Throne and Liberty also runs on two consoles, so neither count is the whole population.

• AION 2: NC’s newsroom release of October 6, 2026 reports 400,000-plus concurrent players on launch day and number one simultaneously on Steam’s Top Sellers, Popular New Releases and Trending Free charts. SteamDB’s own reading of the first day was 397,905, as reported by TechTimes — a third-party number, and lower than NC’s rounded claim for that reason.
• Throne and Liberty: its all-time Steam peak is 336,300, set on October 6, 2024, five days after launch — a figure the game’s own Steam news feed published citing SteamDB. Third-party trackers read on October 10, 2026 put current Steam concurrency in the low thousands — SteamCharts’ rolling 30-day average stood at about 3,950 concurrent players, and its 24-hour peak was under 4,000.

A launch-week peak and a two-year-old live service are not the same measurement, and the second number will fall further once AION 2’s own launch rush passes. What the pair does tell you is the shape of the choice: AION 2 is where the crowd and the fresh meta are this month, and Throne and Liberty is a quieter, established world whose guild scene now runs on committed veterans rather than a surge. The steam charts and player count page tracks AION 2’s numbers properly, including why Steam undercounts it.

Which one should you actually start with?

Start with AION 2 if you have ever wanted an MMO where the fight happens in the air, and start with Throne and Liberty if you have ever wanted an MMO where the fight happens over territory. That sentence is the whole comparison; everything above it is the evidence.

Concretely:

• Pick AION 2 if you want flight as a combat system, a faction you belong to for the life of the character, eight classes with clear roles, a brand-new economy where nobody knows the prices yet, and a service NC runs itself. Check the gameplay overview first, then the pvp page.
• Pick Throne and Liberty if you want guild-versus-guild castle sieges with a real economic stake, morph-based travel instead of flight, a build you can rewrite by swapping weapons, a console version, and a world with two years of chapters already in it.
• Pick neither yet if your only question is population — wait two weeks for AION 2’s launch numbers to settle, then read them against Throne and Liberty’s rather than against a launch-day spike.

And the cheap answer stands: both are free, both are NCSoft, and nothing about installing one closes the door on the other.
