Fair enough... in hindsight Minecraft probably wasn't the best comparison on my part, and I will say once again, I am not a game developer by any means😅 Even if exaggerated, the example was a good one and you have a solid point.
Here's a counterpoint though...
Yes, a Boeing 737 is bigger than a Cesna, and would require a much bigger hangar. I understand the game has come a long way since the initial console release, but I would imagine so have the consoles themselves. So unless the differences between the PS5/Xbox X and the previous generation consoles are strictly aesthetic, the "hangars" HAVE gotten bigger.
I won't pretend to know more than I do about game development, it's well out of my wheelhouse. I would also never want to downplay or minimize anyone's hard work on any game. I've played many that are absolute works of art and I'm sure a lot of blood, sweat and tears have gone in to making them. With that said, I just have a hard time believing that the only reason game developers have gone away from couch co-op is because it would be too difficult, or too taxing on the console. I think the more likely reason is why sell one game and console when you can sell two?
