Best Game Making Software?

One of the things about Unreal is you quickly find what it is and isn't capable of. Unity tends to surprise you when you're halfway through a project, and because it's closed source you can't even attempt to find out why.

Back when I was using it, you could make a variable that was anything and it wouldn't complain, but it wouldn't show up in the editor, and even if you made your own editor it wouldn't save. In Unreal, in blueprint you can only ever make variables that are fully supported by both the editor and serializer, and in C++ it will throw an error on compile if you use something unsupported.

I still think you can nut out a quick game or prototype in Unity faster, but that's because I'm a C++ guy and C++ is just slower to iterate than C# (compile times mainly, 1 second vs 30 seconds makes a big difference over time).
