Running an engine like this in the browser is massively overkill in the sense that most of the code & features are going to be dead weight you don't actually want. You can't actually run any UE5 game in this way that actually benefits from UE5's advancements over UE4 or Unity or whatever, the assets are too big. You're not exactly going to stream 10GB+ of models & textures on-demand. You could build such a thing, but the engagement you're asking from the user at that point certainly justifies just being a native app and providing a much better experience. That said, Unreal Engine is also pushing into the non-AAA gaming domain, and it's possible a smaller, easily run indie game ends up using the engine and still sees value in a browser-based deployment. Something on the scale of Vampire Survivors ( https://poncle.itch.io/vampire-survivors https://poncle.itch.io/vampire-survivors ), although that's using Unity but in theory there's no reason you couldn't do the same with UE5.
