I like these changes, especially removing caps.
I think eventually education/creativity need similar cap-removal treatment, but on a curve so that you never actually reach 100%, but also never max creativity/education.
Anyway, as someone with 11 of the 120 broadcast towers, I really hope this isn't the masterplan for justification of their rarity. I thought 0.1% rarity meant they would do something really special, but +20 income if you also happen to be one of the very few people with voice to skull seems more like a buff to that tech card than to the towers themselves, just to be clear. I think a buff to such a rare tech card is totally fine, but I really want to see the towers do something cool.
In terms of crime, I like the current idea that certain buildings attract crime alongside higher efficiency or some secondary thing like gamer tokens, rather than crime being completely universal. This leads to thematic crime cities and cities that avoid those types of buildings rather than everything becoming generic, so in terms of future crime mechanics I think the best idea would be to double down on casino design instead of deviating from it, because I think they are one of the most interesting things in the game. Beyond that, any 'universal crimes' should be more tilted into the direction of thematic rather than intended to be punishing.
issue is that half of the players just sells crime buildings instead of playing around crime
and other 50% completely ignores crime, cause low penalties
risky gamble on waves towers, now hard to be happy with massive boost.
