Yeah, I get what you mean, if only there was a perfect platform for it, but alas...
This is why I don't personally find mobile, and especially free-to-play as a particularly enticing model to follow. I think charging even just 5 dollars for a game is better IMO. But this is just personal opinion.
Making just smaller free games to build up a following might be a better way to get started. Once you already have a bit of a following you might be able to start capitalizing on that by releasing something a bit bigger for a bit of money, and hopefully things can snowball from there. But this does require that you have a primary income already and that you just plain enjoy making games.
