Well, in that case, every fighting game is turn-based since the different move made by the characters have different cooldown.
No, Skyrim isn't turn-based. Sure some move have cooldowns, but that's normal, slashing as fast as I click would make no sense, and spamming shouts would break the game. Still, I can block when I want, try to evade when I want, bash if I want, do a power attack when I want, and I can actually move while doing all that. In WoW I can move all I want, it won't make a difference, what matter are the skills cooldown, the stats and the dps, in Skyrim I HAVE to move if I want to successfully evade an attack or use an opening, Im not just standing there and mashing my hotkey buttons and clicking on my mouse.
Now you can say that Morrowind and Daggerfall are turn-based as dps and stats are more important in those than in Oblivion or Skyrim.
Yep at its core, using the left or right click mouse or using a key on the keyboard to attack are not much different. Now they said the first 2 skills on your bar are directly related to the weapon you use, and they also said there will be regular attacks, power attack, block, interupts/breakers etc etc , that tell us that combat is going to be action based, no matter if you left click or key click to use them. We know that normal attacks and power attacks are going to be the base of combat, we don't know how these attacks will be activated, ether its left click to attack and right click to block or a key on the keyboard that you can rebind your self that does is doesn't change much at all. an YES shouts in Skyrim are indeed on a global cooldown, as well as powers.
I have a lot of hope for this "action" dimension they announced for the combat. If it's as "alive" as in Skyrim / modded Oblivion, it going to be awesome.
