Aside from being a CN mechanic, one of the better ones if I might add. Imagine that they did something right with their *dead* game. All the lol's
Make infra cheaper to build, or in other words add "peak" infrastructure to the game.
But on a serious note plenty of people have suggested this as well as myself and I feel that if Alex wants to make the game better and discourage pixel hugging this is the best way. An example would be if I bought 2k infra on a city and it gets destroyed to a low of 100 you can rebuild it back to 2k for 50% of the cost. Where it normal costs like $14m it'll cost $7m this of course is without the urbanization projects & policy. The only downside I see is pixel huggers will cry and giant behemoth whales will have a huge advantage but It's worth it.
I'm curious what the rest of you think about this.
