But by 50 points? Couldn’t it at least decrease over time?
Yeah, agree. Could be balanced more with future updates.
It's done this way, because without it worlds would just achieve harmony very fast. If nobody don't like supreme kingdom - wars could just stop forever. Or supreme kingdom pick up others one by one.
Or it would be same as with diplomacy being turned off.
And same for different races thing - done for balancing to "help" civs with decision making. Without it, civs would threat each other same way.
It would be weird if humans prefer to be allies with orcs, instead of other humans, don't you agree?
