Euotopia

Euotopia is a retro 2D multiplayer online MMORPG inspired by the early Ultimas, Nethack, Diablo, gold-box AD&D, Magic Candle, etc.

Euotopia lies somewhere between the realms of action RPGs, MMORPGs, MUDs and roguelikes. It began as a multiplayer roguelike, morphed into a multiplayer Ultima-like, and 10 years later is now a fully fledged virtual world with its own rich history.
