The projects template is getting a little ridiculous... For a start, I'm not sure TSO5 was a project to start with, as all that was produced is a logo... TSOEmu True is apparently a joke, xTSO was created with Windows Forms from badly cut screenshots of the game (Alex interjects: we used FAR archives, IFF archives and the like) (TSOEmu True is also like this), and though TSOReborn may have been a part of history (not sure on this) it similarly did not achieve anything.
Sims Ville Roleplay is actually a (well made!) game, but it's not a recreation of The Sims Online, so I'm not sure if it should be mentioned in this template. If we remove TSOEmu True from the list, that leaves the "unknown" category with little reason to exist. As silly as this sounds, how can you say the progress on your own project "unknown"? (Alex interjects: I agree) I would say it's still alive, in some fashion (still doing research).
