It's close enough. You can use the engine to make whatever games you want, modify the code, rebuild it, etc and profit from the game you create.

You're not allowed to fork and then profit from the engine itself, or the editor. That's a really important distinction, and you're right that it should be highlighted.

But it seems very reasonable to me. Any real game dev won't care about that. Basically, you can't resell the engine, but you can do anything you want with the games created by it.
