combat mechanics will be very complex,following the "d20" system.
As far as i understood by briefly reading through the forum one can switch between 2d graphics and 3d graphics for combat.
Lots of races are planned for dlc/stretch goals,6 for initial release,in addition to minor factions.
Magic system will be expanded from Master of Magic,with even more spells,as well as much more game world spheres as opposed to the 2 from mom.
generally the devs seem to be very creative and friendly people.
graphic is not that important for me for such a game...i still play Master of Magic from time to time and there my eyes are really hurting,but i still like it.Since its still pre alpha and those first screenshots are not much more than conceptual art i do expect them to improve graphics by quite a bit though.
They already said that they will show some ingame playing video example soon and ,very important for me at least,screenshots of the actual playing world and not just combat.
