So for the past few months I have been hammering out gameplay and buidling assets for my game but as I start to dive in to level design etc, the fundamental question is how much gameplay should consumers get for 99 cents or even $1.99? I don't want my players to feel cheated and although I want to create as much content as possible, I also want to keep it polished and fresh without having to overextend my models/texture assets. I know there are no hard and fast rules but would about one to two hours of gameplay be fair? I could create an endless type level or even randomly generated levels but i feel it actually might take away from the type of game I am working on. Ideally, a quality game could be short and still have the player feel like they weren't "ripped off" but there are some out there that want more.
