8-bit GE... What if?

Hmm, I was wondering... Why not make game Editor possible for building and construction 8-bit applications such as NES Games, and heck even an NES port for 8bit games? o.o Of course, it'd have to be a different edition of GE, (unless you had some engenius plan to convert 32bit to 8bit safely, also the mewsics), but I thought it'd be neat ^^
