S.T.A.L.K.E.R. is a series of first-person shooter survival horror video games developed by Ukrainian video game developer GSC Game World for Microsoft Windows. The games are set in the area surrounding the Chernobyl accident site, called ‘The Zone’, in an alternative reality where a second explosion occurs at the Chernobyl Nuclear Power Plant some time after the first and causes strange changes in the area around it. If you are a fan of First-person shooter games like STALKER and looking for more games with similar gameplay then find the recommendations for it below

Stalker: Legacy of Times was an attempt to create a STALKER-inspired game on CryEngine 2, however, its dev team announced its official cancellation.

Anomaly Developers has released a new version of its standalone mod for S.T.A.L.K.E.R., STALKER Anomaly.

Enemy respawns in open world games are tricky to get right. If they are too frequent it feels 'gamey' and it may render a player's in-game actions irrelevant. However too few respawns leave an open world empty, devoid of threat and frankly rather boring.
S.T.A.L.K.E.R. Lost Alpha expertly shows how to handle respawns by striking a near-perfect balance via a hybrid spawn/respawn system. We investigate how this works and how it has made S.T.A.L.K.E.R. Lost Alpha one of the best semi-open world games around. Ubisoft 'et all should take note.
Technically there are NO games like STALKER. It's totally one of a kind.
Fallout 3 would be the closest but it still comes up way short. The other on the list are not even close.
STALKER is a FPS/RPG in an OPEN WORLD Sandbox environment where the NPC's are dam near like real players thus making STALKER feel more like a MMO than a SP game.
You can sit back and watch NPC's fight each other then wait for them to weaken themselves before going in for the kill, you can play Stealthy or Rambo or a combination. You have to Eat, Sleep, Trade, and Craft. Stalker even has Real World Balistics and Physics. No other game on that list offers that much variety.
You can spend a 100 hours or more just roaming around exploring and surviving without paying any attention to the story and still have a DAM GOOD TIME.
If you got a PC then go buy:
STALKER Shadow of Chernobyl
STALKER CLear SKy
STALKER Call of Pripyat
complete them THEN install one the many GREAT MODS like Complete, Reloaded, or Misery and enjoy a whole new experience.
Rage is an insult to every open world game, and really has very little similarity to STALKER.
Fallout 3 is really the only game that comes close, terms of gameplay. But Metro 2033 has a very similar atmosphere.
For those interested in the story, I recommend the book "Roadside Picnic".
