Metro games series

When you get out of the train onto the open snow landscape in Exodus, that is awesome. Such graphically awesome.
I don't like the monsters in the Metro series though. I think they're kinda silly and repetetive (cause there's so many of exactly the same monsters all the time, and it's in multiple of their games), but I never got far in any of the games, so maybe if you get far into the games the enemy types get more diverse.
