Indeed, there is no main quest or even a storyline. But there is a little indicator that there might be in the full release. It seems to me that there might be more to the war than meets the eye and there are also 'dark' forces out there (and they are strong)... Maybe they will work on that.

I don't mind much that the towns are so unfinished, only that the tavernkeeper is so far away in his building.

I agree with rabbit that the best equipment comes from battles. You just need to beat up big groups of enemies. So look around for caravans under attack. They are normally rather well protected and withyou and your buddies you should be able to win against even rather large groups of enemies.
Make sure you do missions for the merchants, they give you 700+ for just escorting a caravan to a nearby town, a lot more if it farther away. Some times you will even be charged with missions to deliver goods somewhere, again at a good price (I accidentally sold the goods the first time and ended up owing the merchants 18600 gold, no trade until that was paid with interest).
Beware of the Sea Raiders though... They are not as weak as their name suggests. When engaging them, be sure to have at the very least 2/3rds of their numbers, and if you feel you haven't got enough, just hire peasants in large numbers. They are bad fighters on their own, but I saw how they dealt with a number of Swadian deserter knights. The knights stormed in, but they were soon halted by the mass of men (and women) and before long they were either dead or their horses were dead. One poor knight actually survived and was ganged up on by 5-6 peasants, his HP and armour obviously helped him a long way as he took hits all the time, his shield splintered and he simply couldn't defend himself, he couldn't even retreat away. Eventually I had to step in and put an end to his misery. But the visage of pitchforks, sickles and clubs striking the defenseless man was impressive. And very good by the way. The knights charged headlessly in and suffered from it. The infantry that followed proceeded to make mincemeat of the peasants until I and my men rescued them.

MP? I can't see why this can't be made, it is perfect for it. The Tournament in Zendar is a perfect setting for it and almost looks like a test for future MP.
