If this is already an Item on the list forgive me...
I looked around didn\'t see it.
Having a pack animal of some sort, like a horse, that could carry you and your gear would of course be useful.
But it would also make for a whole new set of game play and character development.
Sure your high level but, you walk on foot! ... Ha!
First,
Resource management: Horses cost a lot of money to buy
They cost money to stable if your in town
They Need Food & Water - which if your on the right land should not be a big deal
They can Carry extra Items and a lot of them
Next,
Character Modifiers: Pluses Speed and Movement: You move faster on a riding beast and running sucks! ...duh
Pluses to your Charisma - you are much more imposing on a horse and chics dig \'em
Pluses to attack Characters on foot- if you have good horsemanship skill or basic
War Horsemanship Skill
Minuses to Attack Characters on foot if you have no Horse Skill - Your hanging on for dear life
Pluses to your Armour Rating or Defense stats-horses are big and scary to attackers on foot
Plus,
More Stuff to Buy: Hey I\'ve got cool Armor my Horse or Beast need some too!
Last but not all,
The Right Beast for the Enironment or Character Camel or a War Camel - You could use a horse in the desert but, why...
Ride a Giant Bore or A Giant Swamp Rat - your an evil Troll like character and your a bad A$$, you need an a riding beast to fit!
I know this would probably be one of the last major things to come online but, it would add a whole new aspect to the world.
Please post if you like this idea! That way it might get more attention from the Developers.
