I found Far Cry 2 a little boring, and stopped playing. Far Cry 3 caught my attention from the get-go. It's the best FPS I've ever played - got it platinum'ed in the end, I think. It was beautiful, it was fun, and the villain was amazing. There were a few moments in the game where the choice of music just gave such excellent feels. Was it easy? Eh, I don't care, so long as I'm having a load of fun.

Far Cry 4 was great, too. Not quite FC3, but still really, really good and better than most other FPS titles you'll get out there today.
