Whenever I don't play a game for THAT long and come back to it, I just start over. Call of Prypiat is such a great game. I tried playing it recently-ish with the Misery 2.0 mod, but I gave up on that. While I like certain aspects of the mod, it completely ruins the game in other aspects. I'm all for making the game even more ruthlessly challenging, but some of the changes are just plain ridiculous. The rate at which items wear is insane. The toughness of some enemies is insane. I mean, I don't care what kind of helmet they are wearing, no human should ever survive 3 headshots from a SVD. That's ridiculous. Then there is the part where I'm at the very edge of my range with the SVD, where I can just barely even see enemies through my scope on my SVD and they are somehow hitting me with almost perfect accuracy with assault rifles at that distance. Gah. I'm going to play the game again soon, but this time only with maybe the Atmosfear 3 mod.
Edit: As an aside, the S.T.A.L.K.E.R. games are in many ways a lot more role playing than most RPGs.
