Yeah, I couldn't get into STALKER. They need to do something to not make it so fucking boring. I got pretty far, I think. Stopped after you get to that zone with all that radiation. I think it's the second or third town. The one where you can fight people in a cage or something... Anyways, it's a boring game. The world just feels so lifeless and boring.
Did you install the Complete mod?
It gets all kind of hate on this forum, but it seriously is the best and only one to go with for Shadow of Chernobyl, or any of them for that matter.
You either like the burned out, post USSR setting or you don't.
I have looked at all kind of pictures of the real Chernobyl Exclusion Zone and it's a pretty faithful recreation.
Without the Complete mod, which includes a major graphical overhaul, the game looks like complete shit.
If you want a damn hard challenge, Misery for Call of Pripyat is good too, but the graphical changes are way more washed out and not as nice as Complete IMO.
Also, for all of the love that Misery gets, they still managed to fuck up the inventory (non-stackable items) and you can't run more than five feet without being crippled by exhaustion (I can't remember if this was because of a lower weight limit or because the mod decided that distance running was "unrealistic").
