Was one thing that really grabbed me today on their video. the constalions Skill trees, like Thief, mage, tower and so on, looks really good and cool for specalization.
Also the imperial city, looks amazing. Each side has an entrance but has to gain control to enter. there are sewers and many different districs to control, Imperials need help and offer you quests to fight Molag bol. You can control of the market Distric for control of special stuff like creating Imperial Daedric gear. Just alot of cool stuff here.
Also they showed alot of new armors, including glass. New group zone and new solo zone.
Justice system lets you steal, if you get caught you are in trouble, if you steal enough or kill innocent NPS and become (bad).... (good) players can kill you.
Just alot of amzing stuff they showed. this changed alot of people prospectives on the game and made alot of people want return
