I think it would be really cool to have either: * An automatic achievement for being a backer on the project * A set of achievements that can only be unlocked if you were a backer of the project * Specific things that can be unlocked in-game for being a backer (non-game balance altering, but neat objects) This can't work for every proposed version(?), but for versions on systems which have an achievement mechanism in place. I only know of one other game so far that does this ("payday" - http://steamcommunity.com/stats/PAYDAY:TheHeist/achievements/), which there are hidden achievements for making great user-submitted contributions to the game. These also unlock specific items in the game that are otherwise unavailable (a set of unique, ultra-rare, in-game masks). Thoughts?
