-"Recreateing the freedom Elder Scrolls players expect within the World of Warcraft-style mechanics Zenimax Online is using for this MMO would be impossible without changing the way that players interact with the world."
-As such, the game uses a hubless design
-For example, you don't necessarily pick up a quest to do the following, but if you kill all the necromancers in an undead barrow, a shade you free at the end will reward you.
-However, to help you find these events, various NPCs you talk to will tell you where they are happening and put a marker pointing them on your map, which is obviously totally different than receiving a quest.
-The game features three faction PvP where you fight to take over keeps and use trebuchets and other siege weapons to help do it. At the high end, you can have 100 v 100 battles. There are also farms and mines you can try to take over. Mots of this happens in Cyrodiil where your goal is to take over and hold the Imperial City to get faction wide bonuses for it. If you have played Dark Age of Camelot, this probably sounds familiar. For those who haven't, essentially the entire zone is a giant PvP area will all sorts of points of interest.
-The most accomplished PvP player on your faction becomes emperor whenever you take over the capital
-Back on the topic of the skillbar, you have a limited number of skills you can use at any given time, and can change them whenever you're out of combat
-The number of skills is equal to (paraphrase) "a light and heavy attack with your current weapon that take up the first two slots, a few more spells related to your class, and an ultimate in the last slot".
-For example, a rogue can put oil on the ground that a mage can set on fire
-A fighter can also spin in the firestorm a mage puts down, which sends out fireballs
-If you've seen Guild Wars 2 videos, ALL of the above will seem familiar
-The combat model will not be real time due to latency
=( What does this mean?
-The combat is based around a stamina bar which you can use to sprint, block, interrupt, and break incapacitating effects
