wow i don't think half the people in this thread know the definition of profit. Even so the answer is probably WoW, yea there are expenses involved as well but millions bought the game, then the expansion, then paid the monthly fee for years.
You could argue wii sports and say that many people would not have bought a wii without it, but that's not an easily measurable statistic.
currently playing: Skyward Sword, Mario Sunshine, Xenoblade Chronicles X
