What's happened with FC2?
It's rubbish, sadly.
Totally different dev team, as the guys that did the original FarCry went off and made Crysis.
FarCry 2 actually has a lot of potential, but is completely ruined by re-spawning guard checkpoints that you run into literally every 60 seconds and the fact they thought it would be a good idea to give your character malaria and force him to have to track down medication for it throughout the game.
