It was a great surprise when GSC Game World announced S.T.A.L.K.E.R. 2 in 2018, given that they previously scrapped it when the studio essentially shut down in 2011 and its makers had long-since left. It's simultaneously a) less and b) more of a surprise to see GSC Game World announce S.T.A.L.K.E.R. 2 again in 2019 because a) we knew b) wait they're announcing it again?…
