I'm moving on to brotherhood next and I'm trying to figure out which one should I buy. Is deluxe edition worth the extra cash just for some skins and costumes? Or even the 2 additional maps?
Yes, worth it, at least right now, all multiplayer features should be fixed. I contacted support with request to fix the link to the server, so all dlcs, activatable bonuses will work as well as extra missions, which were bound to dlc/online connectivity. So they finally did it, I'm glad.
