I want several things
I want a DLC house.
I want a good 12 quest questline that has something to do with Talos
I want a few unique weapons and armor
I wouldnt mind some added overland monster races like goblins and minotaurs
I want a lot more things for my characters to spend their gold on.
I have come to think of it as the Moneybags DLC.
Things to do with your houses - improve/expand/display options/hirer staff/etc
Buy a castle or a boat - improve/expand/display options/hire staff
Buy better horses/horse armor/armor dyes
Improvements to cities/guilds you are in charge of - improve/expand/hire people/etc
Become patron/sponsor of things - the orphanage, an explorers club etc.
Plenty of other good ideas around. By a farm, build/rebuild a town/fortress/trading post etc.
