Yo, if you get the ps3 version you also get the pc through steam with a code that comes with the ps3 game, so if you play on pc only, get the ps3 game and sell it to someone. If you just play ps3 get it and then sell the code to someone that plays on pc. Its obviously a better idea to get the ps3 portal 2 game, cause you are getting 2 games there (PC, PS3).
