Although the average tends to be a decent amount over $1, 25 cents will secure you a drm-free copy with no keys should games release on desura, steam or other platforms going forward. At least that was the way last time I checked. There is very rarely a reason to pay less than $1, so I think a lot of us forget about that.
Yeah I messed around with it and I see how I got confused. The Desura key part doesn't "light up" until you hit $1.
So that explains that.
Well, good thing most people seem to go $1 or more.
I don't think I will tell the rest of my team that some people are buying it for less than $1. As hard as they worked on the game I think that would crush their hearts.
