Most of us that quit realize we'll never make a quality game unless we spend a great deal of time on them. If you're finishing an RPG Maker game in a few months, your game is probably crappy, unless you spent 8 hours a day on it, everyday. In which case you need to go outside.
Major game companies have dozens upon dozens to hundreds of people working on a game, and spend sometimes well over a year on a game before they release it. What makes you think you by yourself will make an awesome game - or even decent?
