Which games should I play?

Hi everyone! I’ll give you a little background and then I will explain my question. I’ve recently come across Stalker OGSR and I’ve been having an absolute blast with it. The feel of an old game but with enhanced graphics, accurate and powerful gun animations, sounds, weather, it certainly has everything that clicks with me when it comes to the type of games I play. I am a huge Metro trilogy fan and I never thought I’d find something to match that experience until now. To get to the question, what I’m really asking is this: Is there a similar version of OGSR for the other two stalker games? (Call of Pripyat and Clear Sky). One that has the same graphical enhancements, great animations and level of immersion that I’ve gotten from this version? Or should I go for the enhanced editions that GSC launched?
