i wonder how gameplay and combat will be like...
i guess combat could be a bit like terra (or like neverwinter online?) with mousebuttons for normal attacks and hotkeys for skills (so not like gw2 that is mostly hotkeys or vindictus that is mostly mouse buttons)
and game play... maybe a mix of gw2, rift?, skyrim and Dungeons and dragons online?
gw2 with the big pvp map and 3 factions fighting for the main town and farms and villages on that map.
"normal quests" could work out similar to gw2 quest lines too. i.e. you get to a random village and a villager runs up to you and tries to get help for "random quest line XYZ" that is happening nearby.
and forts could be often changing owners (kind of like some gw2 areas) from bandits who take it over, then military tries to capture it back so its under military control... maybe sometimes some bigger monsters kill everyone so a fort ends up deserted and later maybe undead get raised so undead are everywhere this time.
and maybe you can get different quests to help one group or the other to capture something. (i.e. a thief char might pick up a bandit quest to support a village raid, then later another player picks up a quest from the village to get the supplies back from the bandit hideout fort. and if he fails maybe the next would be a quest where the military tries to take over the fort).
rift mechanics could be randomly opening oblivion portals that throw out monsters that attack nearby forts, farms, villages... and maybe kind of terraform the land (visual) the longer the portal stays open. as the daedric prince seems to play a bit story role in this one i guess he could randomly open portals and cause chaos for a area for an hour or so. maybe an attack totally destroys a village (all villagers killed and houses destroyed) and then after someone closed the portal the village is deserted and nearby areas create quest lines to rebuild the village etc.
skyrim mechanics could be randomly created quests you get from tavern people? maybe you get a choice what type of quest you want (combat, exploration, rescue, escort, etc) and it generates a quest line for you depending on the surrounding areas and who owns what (i.e. forts and bandits or caves and criminals or monsters etc) so it maybe creates a combat quest to clear out a cave from spiders or a exploration quest to find a thief in the nearby mountains or to escort some more soldiers to a fort that is under attack.
what is in oblivion gates could be kind of randomly created too (gw2 fractals?)
and dungeons&dragons online with how there are dungeons everywhere and how they are designed with traps. i.e. the inside of forts, caves, oblivion gates, the ayleid (?) ruins (if there are some not sure in what time it actually plays... i guess some time after oblivion? if the imperial city is kind of destroyed by that daedric domination prince).
random quests you get could also "auto adjust" the difficulty depending on your party size and how many other people are in the area around the quest. with maybe hints that something might be too hard for you alone (i.e. if there are 10 people around but just you bother with the fort attack or so, but then i guess "failure" could open up new quests too.).
and quests you get for dungeons are adjusted too for your party size.
so if you take a quest alone it might be something like a skyrim 1 player 1 map cave explore quest, but if you have a party of 5 people the cave might be a whole 3 map dungeon filled with vampires and end bosses.
