I left the console scene around '99 to join the PC gaming world and I've loved it. But there are just some experiences on console no longer worth passing up, so now I play both. I got a PS3 recently and I'm actually mad at myself for now getting one sooner. My PC games consist of FPS games and NBA 2K(which is fun to add all kinds of patches such as jerseys, cyberfaces, sneakers, etc.) but trying to play against others online can be frustrating because of people's different specs and connection speeds.
Plus EA stopped making Madden for PC after Madden 08. They lied to us saying that they would take a year off in 09 and come back to the PC with Madden 10 which did not happen. I know a lot of PC gamers don't play sports games anyway but I'm a sports fan so I need my fix. Plus they don't make NCAA, Boxing, (worthwhile) Wrestling, and (many newer) Fighting games on PC, so I need my PS3. Marvel vs Capcom 3, Street Fighter X Tekken, and Tekken X Street Fighter on the way soon!
