The FX chip in Starfox was cool and all, But Guardian on the CD32 was almost the same graphics-wise without the chip.
You do bring up a good point though. I'd say the expansion port on the CD32 would have given birth to several game-specific add-ons though. Granted, that would be more cumbersome to swap out etc. then having the chip built into the cartridge and require parental help.
