> Every game engine has a sort of "grain" to it where it tends to produce games with a certain look and feel.
I think this is a bit of a myth. Unreal gets this criticism a lot, but it's usually because many studios choose to stick close to the rendering defaults, which does lead to a certain look.
To that point, it's probably a lot cheaper to configure Unreal or Unity into a unique "grain" than it is to develop your own engine. It's also possible to use custom physics instead of those built into the engine.
