A pretty average and outdated game. Follows linear missions with no sandbox gameplay to speak of despite big map. Lots of annoying missions such as stealth, tailing or races.
Clear Sky is the least popular of the 3 Stalker games for a number of reasons. Some people mark it as their favourite for it's interesting attempt at dynamic faction wars and for it's higher focus on combat compared to the other two games. Unfortunately, even after many many years of community patching, the game is still an unstable bugfest. You will find that all your save files may randomly corrupt - assuming they don't corrupt when you enter the Limask area. Since there's no guarantee that even with a solid community patch set chosen from one of two or three solid contenders the game will actually allow you to finish without having to restart from save corruption, I find it very hard to recommend the game. In my opinion the other two games epitomize the Stalker experience better anyway, focusing more on exploration at your own pace - where Clear Sky kind of badgers you with constant updates about faction wars and pressures you into rushing through areas. This is assuming you aren't pressuring yourself through an area because you know it's notorious for save corruption, which is not a much better reason.
