5% is absolutely a fair price, even a great price. But it's a lot compared to free of course. For some games this is millions or hundreds of millions of dollars which is objectively a lot and hence *not worth it. Unreal is also not definitively better than Unity, which is really good. Anyway my post shouldn't be taken as a criticism of Unreal but rather telling Unity that they should be more like Unreal rather than the other way around.

I guess only when developing their own engine is cheaper for them.

Developing their own engine isn't the only other option, Unity's model where you pay a flat-fee for the engine regardless of your sales is another, and if the game is selling really well, that is a much cheaper option.

It doesn't appear that there are any AAA titles made using the Unity engine though. It may simply not be good enough. The Unreal engine, by contrast, has many AAA titles built on it, including quite possibly the biggest game of all time, Fortnite.

Not if Unity doesn't perform well enough for their needs I suppose.
