I came out a very happy man after playing through Metro 2033. I loved almost everything in this game; The setting, story, gameplay, music, etc...  
 So I was wondering, are there any games that are similar to Metro 2033 that you guys think I would enjoy? 
I know that the S.T.A.L.K.E.R games have a similar atmosphere and setting, and that the gameplay is reminiscent of the Half-Life games.  
 Any others?

" @Jais: maybe i just cant find one but it seems like there is only 1 switch "

Machinarium is probably the best adventure game I've ever played. I strongly recommend it.

DId you flip all the switches?

The 360 version is good. It isn't nearly as bad as people claim it is.

Valve, I want your babies. And Gabe.
