Clear Sky is often considered the worst of the Stalker games, and it is difficult to disagree. However, that doesn’t mean that it is a bad game. In fact, it’s a great FPS/RPG. The atmosphere, the setting, and the characters are as unique as ever. The shooting mechanics feel great, and the artifact collection is very fun. Clear sky introduces the faction wars, with the player being able to join a faction and conquer territory. This is actually very fun, and I’ve spent many hours helping out my allies taking over enemy territory.

Add to this that the game costs $10 (or $2.50, when I bought it during a sale) and this becomes a no-brainer.
