I don't know about you, but I just loved my Atari 800 and the original NES console. Some of those early 8-bit games were incredibly fun. Don't get me wrong here, I love the graphics capabilities of newer hardware, and all the very kool game-play of modern graphic game engines. But there is something to be said for the classic's.
Personally I think the reason is developing an 8-bit style game as an Indie Developer, is much easier and you have the opportunity to reach a much larger audience. There are some really great game development tools available on the Linux platform. It's time to start exploring them.
