I’m curious now to see what differences could be noticed if someone made the same, exact game, but 5 different times on 5 different engines. I feel like most of the differences between game engines that would be noricable to a player are mostly just visuals. Like if one engine didn’t have dynamic lighting and another did, that would be noticable. But if they just handled math problems or other things behind the scenes like that differently, I doubt many would be able to notice.
