AION 2 smashed its way onto Steam with a 397,905 concurrent player peak on launch day, October 5, crushing its Early Access high of 171,530 by more than double and beating NCSoft's own Throne and Liberty record. The free-to-play global rollout on Steam and the PURPLE launcher sent it straight to the top of Steam's New & Trending and Top Free to Play charts while ranking among the year's most-played titles. Twitch went nuclear right alongside, with stylishnoob4 racking up over 933k watch hours and pulling peaks near 30k viewers as the Japanese streamer dominated the category.

Early Access required Founder's Packs, so the jump to free-to-play exploded the numbers — SteamDB clocked the exact 397,905 peak, and NC claimed it crossed 400k including PURPLE users. Wishlists already sat above 1.3 million before launch, and the game held #1 on global Top Sellers during the paid window. Current active players hover around 320-350k days later, proving it didn't just spike and ghost.

stylishnoob4 isn't alone in the spotlight — other big channels like KanonXO and shroud piled on hours, but the Japanese creator's streams defined the moment with back-to-back marathon sessions titled "aion2 二日目." Community chatter on X highlights the aerial combat and character creator as big draws, though some Steam reviews (sitting at Mostly Positive around 61-65%) flag optimization gripes and pay-to-win concerns. Still, the launch numbers don't lie — this MMO is eating right now.
