Not so fast. It seems bitComposer did not acquire the rights to the S.T.A.L.K.E.R. game franchise, but rather, the rights to make a game based on the short story Roadside Picnic and its subsequent film, Stalker -- both of which inspired the GSC S.T.A.L.K.E.R. games. Confused? It appears bitComposer is as well.
In its press release announcement, bitComposer repeatedly used the name/acronym S.T.A.L.K.E.R. and even referenced the previous games in the franchise. But according to GSC World's official Facebook page for S.T.A.L.K.E.R., bitComposer did not acquire the rights to the trademarked games.
If this is the case, it appears bitComposer made a huge mistake -- and likely shelled out a significant sum of money -- to make a Stalker game not a S.T.A.L.K.E.R. game.
