I play most of my games on the PS3.
I highly recommend PS3:”Fallout3” (very fun and addictive).
PS3: “Silent Hill - Homecoming”(scary as hell... don’t play it late at night in the dark).
PS3: “Star Wars - The Force Unleashed” (The game opening is worth the ‘price of admission’).
PS3: “Call Of Duty 4 - Modern Warfare” (On of the missions you get to control an AC130 Gunship!!!!! Need I say more).
I believe all of the above games are available on other platforms. My experience with them is on the PS3.
PS3 : Warhawk!!!! Great online combat game. It does take a while to get used to. You can fight as a trooper, tank driver, pilot...it has it all. You can get it for $30 new now (typically $20 used). I assure you that you’ll have fun :-). Also, if any freepers play this, please PM me as I’d like to set up a clan or possibly join your’s. My clan is currently called [AIDS] (long story) but I am more than willing to change that :-)!
