Well those I can answer

1) Unfortunately, we don't know yet. At the moment we're talking with a few parties who could collaborate with us to publish the game. We're using the demo to show the game to them and things are looking positive for that, but it's also the reason why we've decided to put the public release on hold until we know more.
2) Managing your soldiers is quite important. Without your directions they'd attack everyone the can, which can get them killed quite fast. And without assistance of your own men you'd have a really hard time (and later in the game even impossible) to win battles. It's been a looooong time since I played Overlord so I'm not really sure how they compare, but I hope you have your answer, otherwise let me know

3) At the moment picking up other weapons is not possible in the game. The seven feet sword is Great Piers trademark of course, so we've decided to let him keep using that from the moment he gets it.
4) Yes, absolutely! Your task is to liberate Frisia and in order to do so you'll have to set the cities free. In the cities there are many civilians walking around, doing their daily business and sometimes giving you (side)quests.
In the demo there will be civilians as well. But in the scenes you play in the demo you are fighting your way through a town and battle is going on everywhere so they won't be handing you quests. Instead they're running around in panic
