How many of the new games (that looked better) had better circuitry on the game cartridge? I didn’t have a Sega (NES!), but cartridge systems could potentially have a lot more options to work with than the base system. For example, the Pokémon cartridge for the gameboy had its own battery powered memory (IIRC). Not to take away from your argument - the more you know a system, the better it can be exploited. However, in those days, it wasn’t always as simple as it seemed. This was especially true when you were (effectively) plugging expansion boards in with every game. Here’s an example from the NES side: https://en.wikipedia.org/wiki/Memory_management_controller_(Nintendo) https://en.wikipedia.org/wiki/Memory_management_controller_(... The reason why Super Mario 3 looked so much better than the original has a lot to do with evolution of these chips (on the cartridge).
