What are some games that I should get?

[Maurice Moss]

I want to get some single player games. I made this thread because I want to know what you guys think are good games for me.

My time range of release is from 2007 to now. Good graphics are a must

I like first-person shooters. That's primarily what I want. I want them for PC. My computer's specifications are:

• CPU: Intel Core 2 Quad Q9300 2.7Ghz
  
• RAM: 2GB
  
• Graphics: ATi Radeon 4650 HD
  
• Hard Drive: 1TB
  

Tell me what you guys think are good single-player first-person shooters!
