Far Cry 2, A bronze trophy for collecting all them conflict diamonds, just doesn't seem worth it, I gave up on the game at a similar percentage as you, maybe I will try it again one day, when I have time for it
Easy choice! Do what I do - until you've got a certain amount of your incomplete games finished, don't buy anything new that isn't already on your wishlist, unless maybe it's heavily discounted & unlikely to be again any time soon.
