Personally i think Killzone 2 is a great game i play it every day online. Very fun. Deffinatly worth to play

for FPS right now i think Killzone 2 is the best. There is inFamous that will keep you busy for a while too.

well for now i would probably get inFamous and Killzone 2. Those will keep you busy for a while. Then later on Soul Calibur 4 GOW3 and it goes on lol

i would rate Killzone 2 in a medium difficulty. The online part is fun tho so once your good enough in single player ull have alot of fun online.

God Of War 3 and Battlefield Bad Company 2

it doesent hurt it to leave it on standby. Its recomended that if you go on a long vacation you turn it off from the back. But from what i know you can leave it on standby overnight even for 2 days thats fine

Personally i wouldt recommend selling any games. You will lose huge and it and get next to nothing. Just start collecting them thats what i do. Maybe later down the road you will want to play them again and ull be glad you still have them
