What exactly ARE the gamemarkets of the world?

kber81 said: Poland with almost 40 millions of citizens means nothing. Most successful game for PS2 - Killzone - 45k copies sold... no, this is not a first day sale - lifetime (platinum edition excluded). Piracy and high prices kill this market totally. The most successful game ever - The Sims 2 PC - 100k....

What are the top selling Gamecube and Xbox games there I'm just wondering
