The Sims Online (TSO) is an on-line variation of
Maxis Software's
computer game The Sims. Released in December
2002, it is an example of a
massively multiplayer online role-playing game. Players control a neighborhood of sims. This variation allows a player to create up to 3 sims but control only one at a time.
After buying the game, players pay a monthly fee to be allowed to play online.
Technically notable is that the Maxis servers behind The Sims Online run the open source software JBoss.
