You'd probably like Screeps then. It's aimed for developers, but it is JavaScript (Con to me, pro to others). Essentially a bot coding MMO.

You can code in a subset of JavaScript too. Even with that in the game, I find Blockly a little bit more usable given the current feature-set in Bot Land right now (mostly the existence of snippets and premade scripts in Blockly). It's nice to get large chunks of code that you can just drag around.

Alternatively, maybe you were referring to some other part of the game when you said you wouldn't want to play this, in which case I'd love to hear your feedback!
