Poked around in your ideas for the scenario earlier noticed that you asked about AI using custom spells it does...
By chance I made a really mean and cheap spell (was intended as a ritual not a combat spell

) and in the following test that AI killed everyone (including me)

was a summon spell and likely there is a reason that most in combat spells are resonably bad or cost gems.
Making a themed scenario with events along a mod/change each turn sounds like an interesting idea for a long time game...
Must think of how to apply it in a quicker game where turns take a couple of minutes...perhaps a yearly change...
Perhaps a small side program darn...so many things to try...but I guess I'll go for a early/mid balance before poking around in that after all the AI's reaching end game is a first priorit

And I do more then enought programing at uni...
