it would be pretty cool to have those game modes in the next TES game....maybe even something like smear the bosmer.
As hilarious as smear the Bosmer seems, no, I doubt there will be such out of place game elements for an RPG.
However, I would not mind seeing an online Arena mode, in which teams of up to 4v4 can fight one another for kicks and giggles. No balancing would be done for the mode, however, so no nerfing or buffing of certain weapons etc. I just think it would be a neat addition, not something to have a whole part of the game based around.
Anyways, I'm going on too far, I should direct you to the http://www.gamesas.com/index.php?/topic/1092018-tes-v-ideas-and-suggestions-166/ if you have suggestions, such as these, for TES V.
