Successfull MMO?
Pretty much all of the MMO are the same. Fantasy crap. I dont like fantasy games, therefore whenever I start playing any MMO (beside Star Wars, or Star Trek) I mostly stop either after few -> minutes/hours/days.
Idea is good, but chances of this project really happening, are low.
MMO are for masses, and we are not such mass.
Mount & Blade have rather limited population, since this game requires skill & thinking (imo), while MMO dont (mostly).
