Metro 2033 was an enjoyable game, but it was inferior to its spiritual brother S.T.A.L.K.E.R., and S.T.A.L.K.E.R.: Call of Pripyat - so I'd keep that in mind before purchasing. Also, to anyone who plays the original STALKER at this point, make sure to play it with: http://www.moddb.com/mods/stalker-complete-2009 . Or STALKER COMPLETE
