Well I guess I'll only recommend exclusives since you have a 360.
Uncharted series - for obvious reasons
Killzone 2 - I know you said 360 satisfies your FPS needs but you should still check out KZ2 especially since its cheap now.
Resistance series - For the exact same reason as Killzone 2. They're amazing, exclusive, and inexpensive now.
Ratchet and Clank - Great games and Tools of Destruction is only like $20 now. A Crack In Time is newer so its still kinda pricey though.
And lastly keep $60 tucked away for GT5 which is out early November.
