Been diving into Warband mods recently and would like to play this next but I'm stumped here. Seems to me like brytenwalda came out first, then the devs were approached to improve upon the mod for pay, adding more features and a bigger map. Seems simple, I should just play the DLC then right? But then why do so many people still play the mod? Are there any key differences other than the DLC being more polished with additional content? Super excited to get my hands on this one! Thanks for the input in advance!

Title, I think i sold it on accident... Am I screwed or can i recover it somehow. This is my first playthrough so I don't know if it's even important. Am I missing out on much by missing that questline?
