Ask HN: Besides Java, what language you'd choose to develop a MineCraft game?

Python would be an excellent language to consider. A lot of MineCraft is based off of features users can add to it. While Java does make this easy, python is more user-friendly and readable, thus encouraging more people to contribute.

The one I'm most familiar with. And I would probably make in entirely web based using html5 or flash.

Any language, as long as it has OpenGL bindings, really.

Common Lisp. Because, why not? ;).

C++.
