Also they have said that the amount of people who actually play anything other than the earliest start date is pretty insignificant. So new start dates end up being a ton of work for pretty much no reward.
What's funny is that I rarely used the provided start dates, I always typed in specific dates to get to certain people, or just to see how things would play out besides the usual 'William the Conqueror invades England for the MILLIONTH time'.
But I get that they didn't want to do every possible date for CK3, but this is CRUSADER Kings and there is currently no Crusades start date. That is just weird to me.
