i think the list is right, those games change the world may be the sims (make my mom play in the computer, i curse the day when i showed to her) and CS (i see people playing CS who actually hates computers) are missing.
Games that change my world:
-Civilization (and later Sid Meier Creations)
-Doom (LOOK he has a CHAINSAW!)
-Wing Commander (my first space sim)
-Deus Ex (so... i dont have to kill everybody? But is a FPS!)
-Homeworld (look, is full of stars!)
-Freelancer (hi my name is Matias and im an addict)
-Dawn of War (they are orks! but... have flamethrowers)
