LOL @ awack's response!
Yeah, since he mentioned the Genesis sports games in here, I'll chime in and say this is why I love the Turbo in the first place despite the Genesis' technical superiority. Back in the day, the Turbografx was well-represented in the game genres that I particularly loved: platformers, action games, shooters, arcade conversions. It was also very Japanese and that quality shone through.
The Genesis, on the other hand, was laden with 2 things I loathed back in the day: horrible US-developed games with drab graphics and croaky sound, and sports games. Sometimes both in the same title.
I'd take my bright, cute graphically-enhanced versions of my NES favourites any day.
