I'd just love to see the loving craftsmanship of the old days come back. You only get that from passionate, hyperfixated nerd programmers. Back when most devs custom built or at least heavily customized their own game engine so it could meet their requirements exactly and each game would have its own real, unique character.

I'm so sick of trawling through hundreds of UE games with the bare minimum of superficial visual crap loosely stuck on the same built in functionality of the stock engine.
