What, you mean like Dreamcast?  Or maybe Neo Geo?  How about Neo Geo Pocket Color?  Master System?  SNES?  iQue?
And, let's not forget the systems where 99-100% of the games sucked: TRS-80, CD-i, R-Zone, Game.com, Studio II, Virtual Boy, Channel F, Arcadia 2001, and so many more.
Okay mister smarty pants. How bout a list? Show me the percentages of crappy versus good on all the systems ever made and then we'll see.
