Distributing games online is an obvious thing to do, but what about dynamic pricing? You could make a website that sells your game at a price that varies according to its popularity. The first 100 buyer get it for $1, rewarding the early adopters, the next 100 get it for $2 and so on.
The system could look at sales in the last few weeks and base the game’s price based on that, trying to find the optimal balance between offer and demand. The more popular a game, the more expensive it is. Old games already get discounted, why not automate it?
