[QUOTE=EmperorIng360] I bet you pixel had lots of ideas for games during the time he was working on Cave Story.
But you know what the funny thing is? He sat down intermittently over a period of five years working on Cave Story, to make sure that Cave Story was good.
One good polished game is worth more than a thousand ideas. [/QUOTE]
Well I don't know much about Pixel aside from him making Cave Story and being a game designer (Or was it programmer?), but I would bet his day job was what really caused the production of Cave Story to take 5 years. If you think about it, it's pretty hard to find free time to be making games on the side, all by yourself and with no resources to work with aside from inspiration. Then there's also the unpredictable hours of game design. Some weeks they'll be working for a hundred hours, others it's a normal schedule. There's also everyday activities, or other ways to spend free time to take into consideration. Granted, the game is polished, no doubting that.
