Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Within A Deep Forest is a great little 2D platform adventure game that'll take up a whole afternoon. The music's really nice as well, adds to the atmosphere.
Gametap have a crapload of free games, mostly old classics, but they're still good, American McGee's Grimm games are good, episodic, and free for the first 24 hours after they're released, http://www.gametap.com/ Trackmania, not technically free, but from now till friday, Bioshock on steam is £3.49, that's outstanding quality for that money.
