<span class="bold">S.T.A.L.K.E.R. Shadow of Chernobyl.</span> At first, I admit I didn't find it particularly interesting... but after the first 2-3 hours, I just couldn't stop. This game is astonishing, probably the best post-apocalyptic title I have ever played! Its depth is extraordinary, and it is believable in every way: items, weapons, setting, factions... the amount of realism is impressive, and the challenge is always high. It takes a while to dive into it, but when you do not appreciating it would be impossible.
I'm trying to play it "as vanilla as possible", with only the ZRP mod installed; my intent was mainly to eliminate as many bugs as possible, and I added only the bedroll (wich I almost never used), the possibility for two characters to repair items (at a very steep price, mostly to "preserve" the unique objects) and the more comfortable menu layout.
So far, I am really satisfied of the purchase! :)
