I love my PS3. God of War 3 and Metal Gear Solid 4 were the two best games i've ever played. Metal Gear Solid 4 is the best game i have ever played and it is, in my opinion, the best game ever created. Infamous is a fun game.. the GTA's are fun.. Sports games are sports games.. Uncharted 1 and 2 are great.. I have Killzone 2 and that's a lot of fun to play and the 3rd one is in the works.

I think PS3 is the safest bet and by far the better system hardware/software-wise.
