After playing the Arena a figurative million times, the introductory announcements are kind of getting on my nerves. Any ideas to get rid of them?

edit the script in CS (half a joke half a sure)

well the mod could be easily done - it's just leaving the part of script of arena out
IDK if there's mod that would do only this, but perhaps in one of mods that overhauls the arena there is a similair fix

so best search for arena mods/overhaul and check if they have what you want...

What! They're the best bit of Oblivion by far!

"Citizens of the Imperial City, WELCOME to THE ARENA!"

Should you wish to remove them, as said above, it's probably just a matter of commenting out some lines in a script somewhere.

Quickly made a mod, download is http://www.mediafire.com/?0s6dp4937fhwymm.

No announcer, the gate will go down (almost) immediately once you approach it.
