I've been developing games using Unity3D for over 3 years now. I currently have ten games published on the Android app store. My first game I ever wrote, 'Isle Survive', has had over 1 million downloads and an average rating of 4 out of 5. I have also written numerous Unity plugins to enable adding features to mobile games like advertising banners and 'In-App' purchasing.
Account packages, haulage systems, mainframe processors, websites... I've done all sorts of programming but now I try to write games and it is so much more fun!
I still remember how excited I was, getting my ZX81 and writing my first few lines of BASIC. Yes I'm that old...
I love how the barrier of entry to game development has been lowered these past few years. I'm sure this has a lot to do with the current indie game explosion and I'm very excited for the future.
