Under the syntactical surface, Lua is really more like Javascript than Python. Unity has support for Boo, which is just a Python-like front end for the CLR. I'm pretty fond of it, myself. I prefer to use it whenever I can, inside Unity and elsewhere. The docs could use a lot of love, but it's still very easy to learn and extremely productive and a joy to write. I rarely touch MonoDevelop / Xamarin Studio; I write Boo in Sublime Text, and find it very satisfying. Another path I've been tempted to explore is to use Moonscript with Gameplay3D, but Unity is hard to leave. I could be wrong, but I have the impression that Unreal is too unwieldy for a solo developer, which is how I plan to stay for the foreseeable future.
