Just think about the various stinks imping horses into the game would cause... Once we got horses, we needs think about horse thieves, wolves, big cats, etc. etc... Griffons, too. They just love horses. Then, of course, some jackass like myself is going to want draft horses to carry more sh... uh, stuff, and war horses with barding, and a handy dandy lance to impale a few Bhaalspawn upon. And lets not forget magical horseshoes, saddle and tack. Must accesorize the accessories, of course. Then we needs add programming to Cespenar, because the horses need shiny ones, too. And can we take them into our pocket plane, too? A human mind might be able to cope with an extra-planar experience if properly prepared, but a dumb beast? I can smell the runny horse poop already. And there's terrain modifiers to be thought of... Horses traditionally do lousy in deserts, so once we get into ToB, we're going to need to start thinking of camels, as well.

In the meantime, walking is simple.
