Oh boy does Clear Sky have some issues. Bugs galore, faction war not quite finished properly and the end levels are just a series of poor choices. Still, though, I love playing it. The game still scratches that stalker itch and despite the war system being implemented without polish I still find taking check points and defending territory a nice distraction. I'd probably recomend checking out one of the overhaul mods that fix a lot of the problems Clear Sky Complete or whatever but if you love stalker I reckon you'll find plenty to love about the prequel.
