It's a good thing the SNES didn't sacrifice Mode 7 for a pack-in Super Scope.
The funny thing about the SNES is it had far better graphical and audio capabilities than the Genesis, but the Genesis utterly smoked it in terms of CPU speed. That was one (probably the only) respect where the SNES was actually inferior. A game like Sonic which is obviously involves a very fast moving character is something the SNES couldn't pull off very well. I remember a lot of the early SNES games which had a lot of stuff going on had some severe slowdown because the processor had a hard time keeping up with it. On the Genesis that was never an issue.
But as I said, the SNES delivered far better graphics and audio, so it was the superior console for more slow paced games like RPGs and Mario platformers and such, but when it came to fast paced shoot em ups, sports games, and of course Sonic, the Genesis had the better CPU to make it happen. In comparison to SNES games, Genesis games looked duller and more dreary. They played blazingly fast and with no slowdown, but they didn't look or sound anywhere near as good.
The question is did Nintendo make sacrifices with the CPU just so they could pack in Mode 7 and 16bit audio and a more vibrant color pallete? I honestly don't know, but I'm kinda glad they did because I prefer the genres of games that the SNES can pull off more beautifully versus the ones better suited for the Genesis. At least we can be sure Nintendo didn't make sacrifices for the sake of a controller gimmick, but on the SNES maybe they did sacrifice power for looks?
