2009 the year of the singleplayer mod, so many great release and so many mods that should be in this list (if it where longer). To be nominated for an award in Best Singleplayer Mod projects need to have been updated significantly during 2009 and be Singleplayer only. Here are the Editors of ModDB's top selection of 2009.
The Nameless Mod
In Forum City, the Internet is serious business. As its name implies, the city is the physical embodiment of Internet forums and bulletin boards. It's more like The Matrix or Tron than Second Life, however, as the troubles of the city are no laughing matter. Embracing the style of Deus Ex, Forum City has as much crime and conspiracy as the world of JC Denton — but most citizens would have it no other way.
is a Mod for Fallout 3. Just started as a small test project to find out the possibilities of the Fallout-3-Engine and growth larger now. This project places a hidden entrance, of an forgotten cube complex, to the wasteland of Washington D.C.
