And you would hear people talking about how awesome it is that a arena has opened in Skyrim, like "Hey, did you know they are opening a new arena? Thinking about fighting myself" etc

And you could create a team to fight beside you and choose how many enemies and what kind of enemies you're fighting and you would have a large audience watching you fight and cheering you on etc. Perhaps add some new quests, like you get captured by slavers and are forced to fight in the arena to survive, using only the tools you are given. Or it can be a choice to be thrown into the arena if you commit a crime instead of the boring jail

I know there are mods and stuff similar to this, but that is also the case with hearthfire, which I also love <3
I personally think people would love it if this came out as new official downloadable content for everyone to enjoy.
So what do you think of this? Would it be a good idea?
