My friend came up with this idea and I think it is excellent, so I am posting it here with his permission. This is an idea for a pricing model for games that I really think could work for indie games.
I wish itch.io would let you do sliding payments (is that what they're called?). For example, you put your game out there and the first person who downloads it pays 10 cents, the next person pays 20 cents, next person pays 30 cents, etc. Early adopters / reviewers get a free ride, and leave comments about whether or not it was worth it, which increases potential value and makes the next person more willing to pay more. There'd be a maximum cost like $5 that it would build up to, and by the time it gets there you'd have a lot of people who played it for cheap and left good reviews.
The MegaBus pricing model.
I would use this if it existed. :P
