games let you take side quests essentially in whatever order you choose but almost all quests have only one way to go through them. games are generally nonlinear FPS games with very mild survival gameplay at best, NLC 7 is a hardcore survival game like very few single player games out there.
mod out there miss more potential than they realize. It is effectively a reboot of the franchise, which is very nice to see considering all three S.T.A.L.K.E.R. Shadow of Chernobyl using its own heavily customized and largely improved but closed source version of the engine, known as Zagolski Hybrid Engine, telling its own story in a very changed version of the same setting (the Chernobyl Zone), and having totally different gameplay mechanics resulting in an almost completely different core gameplay loop. NLC 7 is a total conversion modification built on top of S.T.A.L.K.E.R. universe, the one I predict will never be dethroned.
2 being a hot topic right now, we decided to release our review of what is by far the best product of the S.T.A.L.K.E.R.
