Two of these threads refer to AI difficulty levels, which is something I already am aware about. I know what the AI difficulty levels do. I'm looking for the other difficulty setting- more specifically the world difficulty level. One of these threads said that it effects monster levels and "minor stuff", but I need more information.
Do monsters on Ridiculous level give more experience than monsters on Novice to scale up with higher stats, or are their experience payouts the same but stats are more buffed? Also, are there more monster spawns on Ridiculous than on Novice, or is it the same spawn rate but much tougher stat-wise monsters?
Finally, what are the "minor" stuff? Tax income? City maintainence? Prestige? Tech costs? etc.
