The game offers significantly more content than any other FPS out there, but struggles a little when it come s to the open world. In GSC Game World's long awaited S.T.A.L.K.E.R.: Shadow of Chernobyl, such an experiment in genre cooking has produced some great results.
The idea of fusing first-person shooter mechanics with an open world is a tantalizing one.
