Well, I nearly quit playing during the second mission when I kept dying because I kept doing stupid things and had not yet figured out the game, but then I realized there was a quick save. option If it weren't for quick save, I know I wouldn't have bothered tying to finish. The time it took trying to get around to each mission and then back for you next assignment is just too much to do more than once. I don't know how anyone had the patience to finish this game on the consoles without the quick save option.
I finished it today and my total game time was right at 25 hours and I only found around 90 diamond cases and left several side mission not attempted, so this game has a lot of possible play time built into it. Overall I actually did end up enjoying the game . Not a great game, but enjoyable and a very long single player version, especially by todays standards, It still reminds me alot of GTA San Andreas, but with a solid FPS shooter aspect. However, I felt the ending was extremely disappointing.
The game is not a classic, but I don't think it's terrible either. I believe if they had not called the game Far Cry 2, it would be much better received.
