Im guessin your only lookin for exclusives since you can get games on your other 2 consoles so:

Definately:

- Uncharted
- Killzone 2 (Will have epic single player and I think it will be co-op as well as online)
- Resistance 1,2 (Both Co-Op and Single Player and amazing)
- Metal Gear Solid (Way better than Splinter Cell)

I cant believe all these people are knocking Splinter Cell.  Have you guys read about the upcoming Splinter Cell Conviction (which console exclusive to XBox)?  Its pretty much going to be Assassins Creed in the modern world, with the same dynamic crowd interaction and hero vision that Ubisoft used with Assassins Creed.

Uncharted. That is all.

Besides what everybody else said:

Motorstorm 2 - Motorstorm 1 is great but 2 will be that much better and it'll have Split Screen and way less load times

Syphon Filter - Great shooter on PS1, kinda lost its appeal after the bad SF3 and OS....seems to be back on track with its PSP's iterations though. Keep an eye out for it.

Actually sf3 and os weren't bad (imo). I think they get a bump rap but I was glad to hear the praise for the psp games but then it went negative again when they ported dark mirror to ps2 (something about no blood) but I still bought it. I really hope that if sf4 or 7 or whatever actually comes out in 2009 that it'll be really good.
