Yeah, that's what I was trying to imply. It'll be easier to find talent and replace people as needed, but that can also be a bad thing when you have penny pinching upper management where talented senior devs are let go in favor of cheaper, inexperienced devs.

The idea that before long you may only have a few game engines in new games is sad though.

I completely agree and it's something I've been a bit disheartened with over the last decade as UE and Unity become more and more ubiquitous. At least many Japanese studios still persist in making their own engines.
