Great ideas. Dungeons that evolve over time (like new passages opening up due to earth movement, kolbold mines opening a new portal/section, etc...) would be sweet. This would allow the devs to add on sections, quests, and lore as they are able. A overlying arc could be devloped little by little as the Avatar must proceed further into the underworld over time(episodes) to (fill in epic goal/quest here/save the world, etc) Also, a good idea for crafted junk would be to sell them to a certain faction or town guard/smith to establish a added town buff to residents, etc.. each town or faction could have a ''town defense" XP bar that slowly decreased over time, but could be increased by NPC vendor sales . The Avatar could only get the buff if they are bound to that town.
