Why would i buy donkeys?
Do they carry more crates?(that i would see as the only selling argument sofar^^)
donkeys, Sumpter or Rouncy ....
Sumpter seem to make the starting trade horses, till you could afford Rouncies to speed things up.
chadz please give the donkeys super powers, so they can carry more goods then the normal horses!
give teh donkeys some love chadz
OR
EDIT: In reallife, donkeys are used also in ratehr uneven terrains ... like mountains. How about giving them an adavantage depending on terrain? Horses would be fastest in graslands and desert. Donkeys would be best in Stepp and mountains.
