My Three Questions
 

1) Will there be multiple Heroes, or is it just this misterous Bill Gilbert Chap? Also, are there multiple people to marry, and if so is polygamy or gay marriage possible?

2) Will there be a map editor/random map generator released with the game, or will that be in patches/downloads/expansions?

3) I've read there is going to be a campaign thing as a main feature. What can you tell us about length, cinematics, storyline, or replayability?

1). There will be three types of hero (Warrior, Palladin, Mage). Each of them has own appearance, biografy, characteristics and manner of playing. There won't be polygamy and gay marriages. There will be about 10 potential wives from different races and social classes. A player can have only one wife at the same time, but he can divorce as well.
2). The map editor isn't planned, but there planned add-ons with full-fledged campaigns with new plots, territories and units.
3). For completing just the plotline a player will need about 15-10 hours. The scrupulous reconnaissance of the whole gameworld will need about 40 hours. The units, chests and even some buildings are situated in different places in different games. So every new game will differ from the previous one.

Thank you for your questions!

Thanks for the reply!

Can you name your hero, or is it always Bill Gilbert? I've seen him as a paladin and as a knight, but in all the screenshots so far, it is always Bill Gilbert. Will you be able to command multiple heroes?

Can you change the portraits, or is it only 3 in the game?

Can you play as a female character?

No, Only those, female in an expansion.

You can assign any name you wish for your character and that will certainly be in use by other characters in the game. There will be one main character to control, in battles you will rule with the whole army.
There are three potraits for the hero, each one depending on the character's class - warrior, paladin or mage (and they are all male).
And you can also choose one from about twenty emblems for your character.

Be happy. You can marry a frog, a zombi, a dwarf or a demoness with a lash. Although all of these are females, I think that no one can say the game is politically incorrect :-) After all, everyone has to respect the rights of frog-lovers.

You know, I consider these "portraits" a major FAULT. I'm supposed to identify myself with a hero, am I not? So why not to make several portraits available?
The warrior guy really s*ks. Some would like it, I guess, but every time I see this face, supposed to be "me", I curse game's designers with all negative spells available :-)

Thus, I am forced to choose Paladin, just not to see this stupid face again, but what if I want to play Warrior?

Well how moddable is the game?

There will be no editor in the game. Maybe it will be released later with add-on, but we don't know yet.
But you can make mods by changing game files (thanks to open file format and support of LUA script language). You can look at already made mods for russian version here: http://www.kingsbounty.ru/forum/index.php?showtopic=273 (russian language).
