You're right, my bad. I should have worded that reply better.

I meant it as a tool to help you code etc it's useful, especially if you know some coding. It can help you to say finish a game by coding mechanics you don't quite know how to make work which you can then fix up yourself with the desired parameters etc.

If it helps with finishing your idea of a game (especially if it's something like the first game you've ever made), it's useful in order to learn some of the workflow involved in making a game.
