3d Math sucks sure, but you can't just use an engine and expect to not have to deal with it. It's just the reality of the situation. Also I'm not denying the volume of work gone into Unreal, but I am saying that roll-your-own approach is still possible, because many of Unreal's features are available online. It's just it's up to you to integrate it all. Of course writing a C++/OGL renderer from scratch is not nice, I've done the same myself and I promised myself never again :-) These days C# + Monogame solves all my Language, API and Platform distribution problems and allows for fast iteration during development.
