to make it short: AWESOME!
the graphics are great, but of course you will need an up to date system for it with a good g-card. the setting is of course a matter of taste, Far Cry played on a tropical island, while Far Cry 2 plays in Africa...so it's not THAT colorful anymore, but the light effects for example are really great.
ok, it's a FPS, so: what about the weapons?
there are definitely much more different weapons than in the 1st game, and you can even buy upgrades for them....crappy old weapons for example jam often (priceless to hear your character cursing while he hits the gun with the fist trying to unjam it
), and sometimes they even blow up in your hands... you can also drive all kinds of vehicles, I really had to laugh when I saw what car I got at the beginning: a crappy old Datsun...
so if you like FPS games you should give it a try, it's definitely a LOT better than Crysis....so far I would give it a 8-9 of 10...
