I take it that the setting is still pretty good,after all it was the strongest thing in AoD. Is it an open world like or is it like AoD's focus on starting factions ?
There are no guild questlines as something that progression revolves around. There are faction-exclusive quests and faction reputation, i.e. you can't side with a faction without pissing someone else off.
In AoD the best parts were the Old World locations. No idea how it's gonna turn out. I'm thinking of Mission Control and Environmental Control and Life Support System -- aka House Ecclesiastes. Nice touch.
Which means you have to buy it, even if you're a Slav like me and we don't normally pay for games, or Windows licenses.
