But seriously dude, if you're one of those people who is inspired by The Last Stand or Sonny or something to make some kind of epic, amazing, ground-breaking flash game or movie, then the only way to do it quite frankly, is to DO IT!
Like I said, fail before you get 2% of the game done, but learn. Then next time, you'll get 3% done, then 4% etc. etc.
Lots of failing and getting nowhere, but the experience and knowledge gained is invaluable.
