Far Cry 3 like Games

I typically don't play FPS's. But the giantbomb quick look of FarCry 3 made me want to play it and I loved the game. Can you guys recommend me any more FarCry 3 type games. Basically any Open World First Person Shooters.

I already played Far Cry 3 and Blood Dragon.

I intend on getting both Farcry 1 and 2 from gog.com eventually.
