Because I didn't play FC as a child and thus am not wearing rose-colored glasses, i can say that Far Cry has not aged well. Normally, I'd forgive an older game of a few bad bits, but this one in particular committed one of the greatest sins in the entertainmet industry: it put me off the rest of the series.
I got this game as a 2-pack with FC2, and after 2 hours, I couldn't take the poor gameplay, nonexistent story, and inconsistent AI any longer. I put it down and never looked back. Well, I did try again a year later on an easier difficulty, and with cheat codes, but Far Cry fails to entertain. It tries to pawn off some stealth mechanics, but the AI across the whole map instantly knows exactly where you are if you so much as throw a distraction rock. This forces you to engage in combat, but far cry's gunplay is terrible and unstisfying, plagued with weapons that can't be aimed (yay random chance deciding if you can hit anyone!) and fire frozen peas intead of bullets.
This left FC2 just sitting in my library, gathering dust. I wanted nothing to do with a sequel to the awful mess that is Far Cry. Eventually, I launched FC2 out of boredom, and was floored. Far Cry 2 is one of the best FPS adventures I have ever played. The fact that the same people made both games boggles my mind.
