That free fire pit in all cities national wonder definitely needs to be tweaked, its super expensive and is basically useless in my opinion,
AND it takes up one of your national wonder slots, you'd be an idiot to build it imo.
@Hydro Also that new town watch building (forget the name) - the very early on one that gives you +1 espionage and -5 crime, its too strong or too cheap, take your pick, either double the cost or nerf it to like -2 crime I reckon.
Also is it possible to give some of your housing line some negatives like +

and +

. Ideally it'd be good if these scaled to difficulty level too! This would be a good way to make the mod a bit harder generally.
Some increased waste (for food) and some negative hammers and stuff across the board would be WELCOMED! You guys should take it as a bit of an insult if people can beat your mod on deity.. this shouldn't happen basically ever. One of my pet hates is when games are too easy, take Skyrim for instance - excellent game - but so friggin easy even on master difficulty. Its therefore unplayable unless you mod the crap out of it.
Take donkey kong as another example, the old school arcade machine game. Its one of the most popular games in history and people have dedicated there lives to perfecting it and trying to get world record. This is because its sooo difficult. Basically only 1 or 2 people in the world have gotten to the last level.
Take Starcraft as another example, extremely hard to play and even harder to master. Players require 300 actions per minute to be able to play at a competitive level internationally. Again - one of the most popular games ever made.
