Messy1's post about wanting more than 3 bard songs made me think. Why not have users generate songs.
For example:
Once a year Bethesda/Zenimax runs a song contest; while in game there is a Bard's festival. The 10 top winners are announced at the peak of the festival and consequently bards sing their songs throughout the kingdoms. Withing 3 years you step into a bar and to hear any of 30 songs.
With war in full gear, contest between black smiths could be held. Armor and weapon designs all provided by users.
So many users on this forum know a lot of TES lore why not have book/story contest? Talk about an Easter egg. OMG I just found a book a guild mate wrote.
Morrowind was one of the first games to demonstrate the power of the community. This tradition continued with Oblivion and Skyrim. I would argue that TES games and user content is synonymous. With a little creativity Zenimax could harness the community.
