It just needs a more accessible layer on top of the JS code.   I've been using it for my campaign, and despite the bugs and complexity, I see a lot of good qualities. Heightmaps, for example, are super fun.

I would add (see below) to _CIV_DISPLAY_NAMES in civ_data.py, because if you are using 0ad 28, they are pers, but if you are using 29, they are achae "pers": "Persians",  

Another thing, I changed the current map, but on the convert page, the Test in Game button stayed the same, instead of changing back to Convert. Also, a stop button would be nice in the convert section

Also, it says in the Analyze section under Resources that food is not counted. I guess, why? Is there a certain reason why you didn't count it? Also, the tab Analyze is spelled wrong. It is currently spelled "Anaylse" (replace the "s" with a "z") 

@Grautvornix, so I was getting some warnings and errors from a certain things on the map which weren't in the base game, then I loaded the game and the mods folder, but the warnings were still there. They didn't go away until I restarted the program. If you could make a button so you can refresh the errors. Also, if you could be able to edit certain things, like description, what civs the players are, if the players are bots or humans, ect. I think that would be helpful, so you don't have to have both this and scenario editor open at the same time, to make some of the smaller changes. Hopefully you don't think that I think this is horrible, it is just my feedback, to make it better; I think this tool will be a pretty usefully helpful
