GAME 2.0 - Update

I think that many online multiplayer games (specifically of the MMORPG kind) already are in a 'Web 3.0' stage, and that this category will dominate much of the discussion on where interactive media and channels are going for the coming years.This is the only category where I don't dump all my research in Everything 2.0 ;-)
In this list you'll mainly find samples of small web-based games with one or more typical 2.0 symptoms.The recent craze around
Second Life is proving my point: the best MMORPG's are about being and having - and that's exactly what makes them Web 3.0.
