Far Cry was just great. Sometimes, I've just stopped to watch water, sun or whatever :D - 8/10
Far Cry 2 could be great game. But it isn't. Few annoying things destroyed whole feel of the game. First thing - constantly respawning enemies. Even if you burned some place to the ground, there were fresh load of enemies every time you came back there :/ Guys in jeeps were annoying like hell too. But biggest problem was about gameplay. 'Missions' were boring like hell (drive somwhere and kill somebody), searching for malaria medication (or smth, don't remember) was pain in the ass, etc. This game was just very boring, technically great game. I just finished it because I wanted to see if something changes later on. It didn't :P So overall - 5/10
You forgot to mention the fact that you die WAYYYY too fast. Hell, EVERYONE dies way too fast.
