Makes total sense for you guys to up to $1.50 and $1,25 for the higher end games, except for----
If you go over $1.00:
Tons of casual players, and not as skilled players, will avoid the game in favor of a game that costs only $1.
Same with parents who are paying for their kid to play, and kids are often terrible at pinball.
This is the market you want playing your games, so pushing them to another game may be unwise.
