I tried S.T.A.L.K.E.R. and sucked ass at it and for whatever reason I assumed Metro was quite similar to STALKER so I never really tried it.  It's right up my alley.

STALKER and Metro are similar in how they influenced different degrees of sandboxy FPS's, I guess. STALKER is more in Far Cry's corner than Metro's in terms of what it does, though yes it can be quite frustrating. Metro is also pretty rough but Exodus is pretty accessible if that's your concern.
