Should I be worried that even in a thread like this we're still having issues with other consoles? I mean, even some of the "legitimate" are somewhat silly. Oh you guys, making me smile.
360: With games like Gears of War, Bioshock, Left4Dead, and The Orange Box, you can't go wrong. Also, you've got a fantastic choice of Live Arcade games to choose from. Let the good times roll!
PS3: It's all about the games, and the PS3 is no different. With strong 1st and 2nd party offerings such as LittleBigPlanet, Uncharted, and Resistance, fun is only a button press away. The Blu-Ray is a sweet add on, and the free online is a beautiful thing.
PSP: This thing can do anything, from playing games and music to downloading your favorite T.V. show. It's portable, the games are good fun, and the enjoyment is always there.
Good thing that I can play 360 and PS3 any time I want, seeing as my roommates have them ready to play. The trifecta is complete.
