Goddamn are you a negative Nancy.
Game Room starts up just fine. Game packs download super fast and it did NOT freeze for me.
Game Room is pretty cool, and I can definitely see the potential. I thought you would have to pay to play, but every game has a free demo version that gives more than enough playtime to get the feel of the game or simply provide a nice "quickie". I bought Centipede and tried Adventure and Yar's Revenge. Great emulation, and the option to rewind a game adds a great new dimension. It's like Braid meets an arcade game.
Can't wait to see what Sega could offer, were they to bring games to Game Room.
