One thing that always gets me about the PC sales charts is the number of times you see a game tagged "pre-sale".
It's interesting, because it reveals a level of dedication in the PC market you don't normally see from console gamers. When you think of a "pre-order" for a game at, say, GameStop, you think of a small investment. $US5-10 down up-front, then you pay for the rest once the game comes in. If, that is, you still want it by then.
But the "pre-sales" offered by Steam and Direct2Drive are something else. You are, in effect, committing to purchase a game weeks/months before it's actually released. That's dedication. It also gives us these strange sales charts, where games that aren't even out are able to "outsell" those that are.
