Gamefly list running low: Suggestions?

I am starting to run out of games to play from my gamefly list since I beat most of them, so I was wondering if people could suggest some awesome games for me to play. (Single player, or co-op)

Some suggested genres:

-RPG

-FPS

- Hit-and-run

• Bioshock 2
• Bioshock
• Dead Space
• Uncharted 2
• Batman: Arkham Asylum
• Heavy Rain
• Fallout 3
• Resident Evil 5
• Killzone 2

All great!!

RPG: Demon's Souls. I've played the game for 20 hrs and only beat 5 of 20 some old levels
