Keep in mind I don't know your situation or what idea for a game you have in your head, but are you coming at this from too much of a black-or-white angle? No

Keep in mind I don't know your situation or what idea for a game you have in your head, but are you coming at this from too much of a black-or-white angle? No you can't create Skyrim iOS edition in your free time, but you could create something much much sillier and simpler right? Get the ball rolling, the creative juices flowing and a few apps in the respective app stores before quitting and going full-force? I realize there isn't anything prophetical here; if you are an all-or-nothing type, then that will just be a much harder decision to make and I am hoping you get a chance to make it at some point.
