Extension to overridden bonuses
Overridden bonuses are good, causing chaos on big maps like the US map, but the limit could be extended to 10-50k, because it can give even more chaos to what happens in the game. (Yes, I have a template for extreme overriden bonuses for the US lol)
This would help for chaotic and fun games with this extension, and I think diplomacy games would work with this too. The only downside is that lag wouldn't be minimal, and there would probably be a lot of it. Other than though, putting a warning before putting overriden bonuses would be good.
So yeah, that's my idea!
