- No worries about system requirements.
- No worries about spending money for those said requirements.
- No DRM.
- Though this generation kind of fucked it up... Consoles used to be easy and fun plug 'n play.
- Easier for local co-op or multiplayer: pick up a controller and join the fun.
- And lastly: the games -> LittleBigPlanet, Resistance, Uncharted, Lost Odyssey, Okami, Viewtiful Joe, Shadow Hearts, Shin Megami Tensei, etc.
And more personally: I use my computers to WORK. On my left side, I've got an iMac with Final Cut for movie editing and a Cintiq hooked up for all my Adobe needs. On my right, I've got a i7 laptop with 16 gig RAM for programming and 3D modeling. When I want to relax, when I want to play a game, I do NOT want to be reminded of work, so I go AWAY from my working station. On a couch, with a controller in my hand, in front of a decade old 4:3 TV.
Now THAT is how I play!
