What Cursed said :) I have a few ideas and drafts for CK2 and CK3 but nothing definite yet. The next game I make won't be CK2, because I need a little break from CK, but will almost certainly be set in the same universe (so no characters from CK, but a few references and easter eggs).
I do have the title for CK2 already, though, thanks to a player on Discord ;)
