Flat and unlimited pricing can often be a problem. Flat means EA pays as much to manage all their game-press for all their games as an indie dev does for one.

Also, I realize you're keeping it simple now but have you thought about figuring out scarce resources (likely bandwidth) and charging based on that? Or, even just setting a threshold at which there will be extra charges. (1GB traffic/day or 2GBs stored.)

When I see a company offer unlimited deals I wonder how long they'll be able to offer that.

Looks neat, if I had a product being released it's stuff I know I wouldn't be as on the ball with as you now are. I'll sign up (even at current prices) if I release anything.
