Fallout 3
and Fallout New Vegas
Now I'll admit, the enemy AI probably isn't as fast or clever as the ones in other shooter games. but It does give you more chances to think, They are shooters though and the shooting mechanics work well, though I recommend you play fallout 3 get used to the mechanics. then play New Vegas, which has a bit more depth and complexity but once you figure it out it's quite rewarding.
