Oh, wow. You are the first person that I know that actually owned one of these.
I only ever saw one game for this platform called Bonk which I think might have come with it. My little brother and I used to hang out in a local department store playing it all day until they would run us out.
I was always surprised that the TurboGrafx-16 didn't really blow up. I guess the NES and Sega Master System were too popular. The TG16 had better graphics in my opinion.
At least I remember thinking that while playing Bonk!
I think that NEC was just a victim of timing because it soon found itself face to face with Super NES and Genesis, and well, it couldn't compete with that.
I did like a few of their games but for the most part they never really stood a chance.
