Does aion need a subscription

Aion, the MMORPG developed by NCSoft, originally required a subscription for access, but it transitioned to a free-to-play model in 2012. Players can now enjoy the game without a subscription fee, although there are optional in-game purchases and premium accounts available that provide additional benefits. This allows players to experience the game without a financial commitment while still having the option to invest in enhancements if they choose.
