I loved the first game, it was called Shadow of Chernobyl or something, great menu theme, very dark and depressing setting but ultimately really atmospheric and cool, i think Stalker 1 and 3 are the most atmospheric games ever made, their atmosphere is thick as fuck, beating any other game out there, even Thief.
But they have certain flaws about them that could've made them much better, you instantly recognize the passion in them, i also loved how smart the A.I was in those games.
I think they need a better shooting mechanics, better world design and better side missions.
This game was made under tough situation, so i think it will ship in unfinished and messy state, i will wait for word of mouth before i buy it. Visuals look sick though.
