Out of over 300 games the FMV games don't take up 5% of that. But that's the reception the system has (for some reason) so i don't blame you for thinking that in the slightest. The CD-i and maybe the Sega CD are the only consoles with large FMV games (not including cutscenes and intros) to other genre ratios. I actually believe the majority of CD-I games are FMV unless you include Edutainment games.
But, uh, people usually don't play those unless they are from Humongous entertainment.
