I concur, MegaDrive, Genesis, PC-Engine -- very kool names for consoles.
TurboGrafx-16... besides being a mouthful, this is pure 80's, as Keranu correctly pointed out. I never really cared for this name back in the day... BUT NOW, 16 years later, I love the cheezy name.
and it wasn't just the name, the friggin' logo, with flourescent green and orange, is sooooooo 80's. It's awesome, dude!
