Ace of Spades Windows game

Ho ho ho Merry Christmas and merry Indie of the Year. 61,772 votes and 3,444,800 visitors over 20 days. We shovelled the punched ballot cards into the local IndieDB super computer, ran our algorithms and watched the computer churn the raw data into our top 10 list. We lost the lives of many talented scientists and computer experts, but it was worth it because now we have something awesome to share with our community.

Your votes have decided this years Indie of the Year and the results speak for themselves.

To qualify for the top 10, the game must place higher than it has in previous years and must have had a significant update in 2011. Otherwise an honorable mention is given, which these teams have received:

Since winning last year Minecraft we spent a lot of time deciding on the placement in the awards. However the rules still apply, since it won last years event it cannot place again. Honorable mention granted!
Amnesia: The Dark Descent A year later is still spooking people! The mods have kept it alive but not enough to place higher than last year!
If you can create a game with the cast options Dwarf Fortress has you deserve to be within this top 100, however DF just missed out in placing higher then previous years.
Only just missing out seems to be the thing to do this year, Mount & Blade: Warband is no different, a few votes more would have seen another placement.
