I've recently (Today, in fact) picked up STALKER: Shadows of Chernobyl after a very, very long time looking at it. Along with it, I picked up Clear Sky in good faith.
Now, I'm a story nut. If something tiny irks me about the writing of a game, it may set me off of it completely. Along with that, I prefer to experience the story in order rather than going 3-2-1-4, like I mistakenly did with the Half-Life series.
So, I want to hear from someone who's played both STALKER and the prequel Clear Sky and given consideration to the storyline. Should I play the games in canonical order (Clear Sky -> Shadows of Chernobyl) or is there something in the first game that would give me better insight to the storyline in Clear Sky? Or does one of the games have such significantly better gameplay than the other that I should play that first and save the frustration for later?
Or is the writing balls and should I be paying more attention to killing things?
Remember, no spoilers. Spoil it for me and I will hunt you down and bury you alive.
