It's a curious way to organize data, but Microsoft's Major Nelson has posted the top Arcade and Indie games of 2010, based on "full versions purchased" during a game's first seven days of activity.

Topping the Arcade list is Dead Rising 2: Case Zero, which definitely owns its place as Capcom's "most dynamic sales weapon" ever. Capcom's other Dead Rising 2 standalone tie-in, Case West, also did some faaaaa-ntastic numbers, taking the seventh spot. Limbo, which was one of our top games of 2010, took the second spot, while the Perfect Dark refresh can be spied in third. Super Meat Boy, prime at five on our best of 2010, hunkered down on this list at spot 17.

In the Indie section, Baby Maker Extreme popped up in first place, followed by several games that have "Avatar" in the title. A game called Try Not To Fart also made it into the list. Check out the top 20 Arcade and Indie titles after the break.
