The more lackluster your first game, the next one will be made that much better because of how much you learn!
One day I will make an RPG. I mean, I've been working on it for the past year or so, but even still I'm always nervous about it being my first one, and thus won't be all that snazzy. I always say to myself that my SMBX games are all the "first ones" and those are the ones that suck. But RPGs are a different beast with a more scrutinous crowd.
