Need help in a new game decision

I'm looking to pick up a few cheap titles until Medal of Honor Warfighter arrives in October.

Thinking of buying one or two of these:

Vanquish
James Bond 007: Blood Stone
Resident Evil 4
MGS: Peace Walker

I'm an FPS fan and I've played Resident Evil 4 on PS2 and Peace Walker on PSP. I like them both, but haven't experienced them on the Xbox 360.

What are some other titles I can pick up under $20.

My current game list:

Spec Ops: The Line -Apache Air Assault -GRFS -Medal of Honor -Crysis 2 -Homefront -MW2 -MW3 -Sniper Ghost Warrior - BF3 - Batman AC - I Am Alive - Splinter Cell Conviction - TRON Evolution

Vanquish is full of exhilarating non-stop action with incredible visuals and sound effects. I definitely suggest you play that, it's awesome!
