The ideal gaming platform would be one where not just the game but most of the electronics that have traditionally been in the console are also in the cartridge. Mass production of cartridges would keep that affordable to the end user. The console would effectively just be the power supply and monitor and controller interconnects.
This approach has many benefits including:
* New games could take full advantage of new hardware and general tech advances.
* Games hardware could be custom tailored for each game.
* Owners would never need to upgrade their base console.
* Cartridges would be practically impossible to pirate cost-effectively.
