Heres the idea that I suggested...
An Arena, perhaps in another plane (maybe in Oblivion, cause ya know, that place is rough) that players would access from within Skyrim at an altar/portal/oblivion gate...
Once there, it would be a place of chaos and dismay where players could show off their armor/weapons/skills and compete or form teams for multiplayer arena matches to appease the twisted desires of a Daedric Lord.
Now I know most people (including myself) never want to see multiplayer in the open world sense, but this could be a fun and exciting alternate take on the whole thing. Bringing together the community and allowing for a badass activity for those who feel like they've "done everything" in Skyrim.
Thoughts? (And please be civil)
