You'd be surprised how much efficiency an engineering team can squeeze out of their games with time and motivation. A lot of bloat happens just to get the game out the door and is then good enough.

While I didn't work on the port itself, the effort that went into the Doom Eternal switch port paid off pretty well. https://www.eurogamer.net/digitalfoundry-2021-doom-eternal-s...

I'm hopeful that working with Nintendo would provide the time, money, and expertise needed to put the effort into making this a solid port.
