Yeah, I'd only do outside areas in Unity. I found out how to bring real-world geometry into Unity as a heightmap.

I'd do buldings and whatnot in Max and then import into Unity as a .FBX or sometting somilar.

Common misconception. It is the easiest engine to use, but making sonething that's actually good still requires substantial skill and experience. And optimizing large unity games is something few can do.

Something I have found to be sadly true. And I only started using Unity because I was fed up with the limits of the KotOR engine. I also played around in Unreal, but it's not as easy.
