I think that your first 10 games should be free. That is because you build up experience as you make them. Maybe by a slight chance, your 11th game should be commercial (if it's that good). I'd say 15 games released and non-released is probably a good number to start on the commercial genre. Just keep working and building up experience and sometime, you'll say, yep, this is the game that I think is really topping other titles and I think I should sell it! it's okay, I'm sure General Jackson didn't mean to be rude. So, cheer up and either improve, or start a new one! I even had to do that for my last game. Good luck!
