32x, I agree was a bad idea with a low number of games released for it. The idea was to upgrade a last generation console and extend its life, the issue is that the SEGA Genesis didn't need either units and technically would have been better off skipping the Game Gear, 32x, Nomad, and CD; while focusing its pure attention on Genesis.
The issue (not counting the 32x) is that everything they released was to challenge competitors.
