Unreal Engine is broken, why do people use it and like it?

For me, this ^^^.

The one issue I DO regularly have is some kind of memory leak (or apparent aggressive caching hoarding of RAM) where the RAM footprint of an editor session keeps increasing. ULTIMATELY it will run me out of RAM, but rarely have I had it crash on me otherwise.

As for gaming, yeah, I’ve had to learn how to really get the most out of it, but I’m lovin’ it.
