I liked very much the AI, sounds, graphics, challening gameplay, enviroment and level design in FarCry 1 (e.g. the carrier feeled revolutionary great). Mutants were silly, but fun, different and challenging. The dark jungle feeled very dangerous with the deadly mutants. Maps were also big and full of little details. Only the ending was over-impossible. In Crysis you were immortal, the jungle was mostly boring. Nothing new to see after demo level. Wherever you went, you couldnt fail. One tree as cover and you could kill 30 enemies without noticing. I didnt find much feeling or interest in Crysis where FarCry 1 felt almost as groundbreaking as OFP (in it´s genre), even I didnt play anywhere as much as OFP.
