what do you guys think and yes i did add pc shared games.

What the hell was that exclamation mark in the title for?

The only game I have interest is Banjo Kazooie 3

It's Tale of Vesperia, not Casparia, and there's quite a bit more than "1 or 2" missing.

X360 games that interest me:

Alan Wake
Bioshock 2
Dead Island
Dead Rising 2
Elveon
Fable 2
Halo Wars
Halo Chronicles
Splinter Cell: Conviction
The Precursors


PS3 games that interest me (haven't dug too deep into all titles though):

Resistance 2

I think everyone knows I love to pick on the 360 (I have been bitter because my RROD came before the Warranty Extension), but I think I am more interested in the 360 list.

No doubt a few games listed for each console here will at some time appear on the rival system.

The PS3 will have God of War 3!

It is better for that reason alone.
