Aion

A South Korean video game developed in 2007 by NCSoft for Windows. It is a massively multiplayer online role-playing game (MMORPG) known for its unique flight system and aerial combat. The game takes place in the world of Atreia, divided between two warring factions — the Elyos and the Asmodians — with a neutral territory controlled by the powerful Balaur race. Players can choose a side and develop their characters by selecting from multiple classes specializing in magic, melee, or ranged combat. Aion combines both PvE and PvP elements, with its core "PvPvE" mechanic involving battles between players and AI-controlled enemies in an open-world setting. The game is notable for its beautiful fantasy-themed graphics with Eastern influences and an advanced character customization system. Initially launched as a subscription-based game, Aion later transitioned to a free-to-play model, broadening its player base.
