You have to buy the DLC from the website, I believe it's called horse armour or something along those lines.
The best horse without the game of the year addition is the Black horse.
Each horse is different, so the best is either the unicorn which can't be a default horse, or the Shadowmere which can be a default horse. The unicorn is the strongest and the 2nd fastest. The Shadowmere is the fastest. The Best buyable horse in Oblivion is the White Hourses (Cheydinhal stable).
For the Xbox 360, you can buy the 200 point Horse Armour Add-on.
a horse costume.
In polka dots? :-S
dressage
yes there is a horse armour mod for the PC version but it is called dlc(downloadable content) on xbox 360 and ps3
Shadowmere can be equipped with armour, if you have the Horse Armour Pack plugin.
I kinda hope not.
I blew them to oblivion with an atomic bomb; they were blown to oblivion; the Universe was sucked to oblivion; its like they appeared out of oblivion
a white dress with feathers on it
