A classic themepark MMORPG famous for flight and its Abyss PvPvE zones. In Europe it runs free-to-play via Gameforge, with a nostalgic, old-school feel.

About Aion

Aion is a classic fantasy MMORPG with a signature twist: flight, both in exploration and combat. Its winged battles and open-world PvP made it stand out, and it remains free to play with an optional premium tier.

The art still looks striking, and the character creator is famously deep. It's an older game, so some systems feel dated and the grind can bite, but for classic themepark MMO structure with aerial combat, it's a distinctive free option.
