The S.T.A.L.K.E.R. trilogy (after applying community bugfix mods) is better; with ZRP, Shadow of Chernobyl was bug-free except for the ending.
Then again, I played the original biggest known as Metro 2033, not the Redux ver. I still think there is more interesting stuff in S.T.A.L.K.E.R., though, overall. The environment is incredible in its natural, unscripted interactions and not… manufactured.
It had a giveaway on Android, and I think iOS, 5 years ago. It’s certainly one of the most creative minimalist games out there, but I just couldn’t figure out how to get up to higher scores.
