METTLEWOLF - I was answering the question, not making it. I posted a link to the GS page instead of the title of the game.

"What game is being played in the background of the Steam web browser?" http://uk.gamespot.com/pc/strategy/defensegridtheawakening/index.html

Nice stuff. I actually caught myself wondering a few days ago why no one made a browser addon for WoW yet. To the people thinking this is useless: Browsing while playing doesn't mean you're bored of the game. It could be anything. Spotting something that may be a bug. Needing some extra bit of info. Waiting for something to happen in game (A raid in WoW, respawn when playing online and there's a respawn timer or rounds, loading screens). I also saw a few comments about getting more RAM and having a better computer to alt-tab out of. Well some games just don't alt tab pretty good. Fallout 3 is one of them for me and I think 4GB RAM should be enough. Oh, and to uberjannie (yeah I know his comment was 2 pages ago): It's people like you, not Microsoft, that are keeping us tied down to 32bits. Microsoft is pumping out 32bit OSes because you're still using them. I'm currently sitting in a room with 3 computers, all using 64bit operating systems (Vista, XP and Ubuntu) and I have zero problems with drivers or software. Sure all my games on Vista64 are running in 32bit modes but if people started using the 64bit operating systems when they started appearing, we would be getting games coded in 64 soon enough. Do yourself a favor and buy a 64bit OS. You're wasting 25% of your physical RAM.
