A couple of things:
God mode works although problems can ensue. Especially with mounts i.e camels, horses, elephants (especially elephants). Like the people will ride invisible elephants, and cant fight on the ground after their mounts have been killed. Ships also sometimes have problems when it comes to damage. An admiral died once, came back to life (god mode) and the admiral death message kept popping up annoyingly. Otherwise god-mode seems to work fine.
There should be instant building cheat for AI nations as well (if only so i don't have to wait for them to build their special national cultural buildings like somerset palace, the Hoffburg, the Brandenburg gate, etc.
A way to edit or give/ take away certain traits/ companions to certain characters i.e getting rid of madness for Spanish start leader, or morally corrupt, adding majestic etc.
Infinite morale (possibly for both sides so there's no running away/ easy to chase down the enemy army, great for total army annihilation)
Infinite stamina (no getting tired, infinite running, etc)
And a way to change how one is perceived/ is loved by all (i.e maybe negating the territorial expansion modifier? Or adds +5000 positive influence from selecting the cheat?)
I think there were a couple other ideas/ improvements/ requests, but I'm happy enough with the trainer. Thanks for it, and if you could somehow incorporate these/ improve the god-mode even further, it would be most appreciated.
