I liked the first Far Cry game a lot, even though the end was crap.
I never cared much for the second game, it still lingers on my Steam library and I have a PS3 copy around here somewhere. FC2 took itself too seriously at times and the perma-death allies were no fun.
I spent the entirety of yesterday just playing FC3 on PC. It's amazing. I just wandered off and started upgrading my gear, capturing radio towers and strongholds. It's just so good. And I haven't even gotten to the story missions yet.
The best bit was with taking over a stronghold that has a caged bear inside it. Obviously I sniped the cage door, leaned back and watched the enemies get mauled, one after another. Glorious. Then the local friendlies get there and the bear takes out one of them too. Heh.
Amazing game. And I strongly recommend the PC version. All the console ports are janky.
