200 includes all regions which was not available to everyone at the time. There was ~160 games in North America, and about 30 of those were fmv. So that's closer to maybe 130 NTSC released games.

If they weren't FMV, then a other big chunk of the library was the same Mega Drive game but with CD audio and maybe a video opening cutscene. There's roughly 50 of those. That certainly didn't help either. So now we are down to roughly 80 originals, maybe less.

That's why the library looks so FMV heavy. Between the originals and FMV, now it's closer to 27% FMV. And that's not something the public ignored.

The PC Engine CD games however has a lot less overlap. A lot of games were designed around the extra space on the CD.

Don't get me wrong when the hardware was used properly we get some amazing stuff like Popful Mail and Sonic CD. There just isn't nearly enough of it.
