ha ha ha ha Herr Koos, you crack me up!!!
well, what a good idea would be is to visit IGN.com or Gamespot.com to check for the latest releases and game ratings to see whether you fit game preference: from RPG FPS, Strategy...etc
from there choosing a game can be really easy, games are rated by numbers of players, and forums to read about how the game performed, game visual qualities and so forth...
if you into Metro 2033 (I know i wasn't), then maybe turn to S.T.A.L.K.E.R. (Shadow oh Chernobyl, Clear Sky, and Call of Pripyat), they have the same setting, atmosphere and visual greatnesses....
but yet again, pay a visit to the websites that offer recent gaming information!! it makes you wonder what to spend your money on next!!
enjoy!! and yes, punctuation does help!!!
