Terra (video game)
Terra was one of the internet's original massively multiplayer online role-playing games (MMORPGs), debuting in early 1996 from Kaon Interactive. Kaon dropped development of the game within a few years and it has since been taken over and kept running by its loyal fan base. It may be the oldest MMORPG in existence. Other than minor updates to run on the newer Windows platforms, the game is still in its original retro format and is free to play.
