Oh whoa! What an amazing tool! I am forever amazed by our modding community.
I love Paradox games but they take DLC's to the extreme - imagine bannerlord but all the factions look the same at launch and you have to spend £5 and wait 6-9 months a-piece to make each one look unique.I have CK2 and all its dlc's, same with Stellaris. and yeah, Paradox quite greedy in that regard. A lot of the stuff they charge for as a dlc, is content you would expect was part of the core content of the game.
That Northern lords DLC is honestly a bit of a rip. I bought it (like a sucker anyway) but it's basically 2 new costumes and a few flavour events that probably should have been in at launch.
