Well, I can't really believe that the money script could unbalance the XAI.
In my opinion, the AI must get some additional money, because of several reasons:
- They don't get missions to earn money
- They can never establish such a good economy as the human player
- I think they don't sack cities and exterminate populations as the human probably does
- Even with the best AI the AI needs some help to make a good challenge and I think that's what most people want
Also, I can hardly believe that the AI can go really bankrupt since they will get much money per script if their treasury is less than 0.
However, maybe I will tone down the scripts a bit, the better the XAI or other AIs become...
