What 2 pick up?

Borderlands is coming out soon and like a number of new titles for both the 360 and PS3 I'm not sure what to pick up ? Graphics aren't really all that much better with Sony's creation and as far as I've experienced online gameplay is lacking. Resistance for the PSP? The week the game came out I didn't see anyone online playing. Same for Killzone 2 on Slim console 3 weeks ago.  "Any Rank, Any Map, Anywhere".  Nothing came up.  At work the guys said I might have been doing something wrong, but you'd never work that hard to find a room with GoW2. Bottom Line: Soon the Wife is gonna' inquire, "What the hell did you buy the thing for?!"
