heres my general rule of thumb
360 - Hardcore gamer junkies
PS3 - Enjoy a competition but also more for fun
Wii - GTFO. or just for fucking around with family/friends/gf.
played all three and personally 360 is just amazing compared to the other two...and games on blu-ray, arent actually better...to my knowledge, theyre actually slower because they have to load it twice onto the disc for some reason...i read it somwhere..
i recommend a 360.
