I know CK2 had a lot of meme stuff, but personally I would prefer if CK3 aimed more for a realistic medieval immersion and not too much comical content like the fart events and that kind of stuff.
I hope that Vic3 will have a much more serious tone.
Supply and demand
Paradox discovered that people follow the creators that make memes on their channel.
Memes are free publicity.
Free publicity attracts more consumers
Consumers give money to the company.
So you most make your games meme-able to earn more money, its simple.
For example the first DLC for CK3 was a nordicist content pack to satisfy an infamous section of our playerbase, but did not added nothing useful to the game in general.
Then Royal Court its all about creating memes, added some small QOL things to improve the game in the long run. While not fixing most of the issues the game has.
The old era of GSG ended a while ago, but we still have these threads, games are made to make money. And companies generally dont care about their "old customers" as much as they care about expanding into new niches, CK3 has more RPG elements than its predecessor.....and we know this from day 1.
Name 1 (one, una) company that makes realistic historical games, only 1 (one, una), and tell me how successful it is. Sadly, memes are the future of gaming, not historical accuracy.
