cRPG is a modification for Mount & Blade II: Bannerlord. It adds persistent multiplayer character stats, hundreds of unique items, an online campaign, clans, duel ladder, a co-op game mode and a few more things.
Here we see a collage of a few screenshots from the recent Polanie siege of the Northern Alliance's Ryibelet Castle
Definitely needs more ladders
Catapults would have been nice to break the walls down. I think I got killed at the top of a ladder like 40 times in this siege ;_;
