Hey Scheffsache,
nice that you enjoy the game :)
At the moment we are only focussing ona single player experience and we will stick with the singleplayer only at least till the full release.Nobody knows yet where the journey will go from there on.
To your points:
– More factions are on their way. The next minor faction will be the Goblins.
– Reputation System is on our List
– horses are on our discussion list, but not decided on yet. Probably they wont make it :)
– dual wielding will not be in for now.
– More races will be added but probably no elves or dwarfes. Just more enemies :)
– Banner Editor, Tabards and a mechanic showing your banner on your shields like in Mounta and Blade are under discussion currently.
Cheers!
