Q: Do you have any advice for newbies wanting to start making their own games?
A: Definitely. Start right now, tonight. Download Corona SDK from Cross-Platform Mobile App Development for iOS, Android and quickly learn Lua and go through their examples and blog posts. You'll be making games in no time. Make lots of SMALL GAMES. Do not attempt anything big at the beginning. Just try to make and complete one small game like Space Invaders. It'll teach you how much is under the hood in a game.
