I read (here, on these forums) within the last 48 hours that devs don’t set the prices you see in the store. Those are set by the publisher. The developers have suggestions for the prices, but the publisher is under no obligation to honor those suggestions.
As for the overpriced thing, I agree. However, I am certain that I am not the target audience for these. I don’t make enough money to whale out on these games, but clearly someone does. The game wouldn’t have lasted this long if people weren’t buying stuff, and they have been buying at the current prices.
