Are you being intentionally dense?
I'm talking about the combat and world interaction mechanics. IE things like how you fight, with hotbars and clicking on targets then everything happening with background math. MMO combat is more akin to a strategy game than an action game. Whereas TES is most definitely an action RPG. I seriously challenge you to name ONE single player game that mirrors the combat mechanics of your standard MMO.
Maybe I'm older than you. I played many, many, many RPGs that were not real time. Starting with Wizardry, probably. Bard's Tale, Ultima, Might and Magic, seriously.. dozens and dozens. That said, I've played the more modern games like Skyrim and Diablo, and I can tell you, hands down, the combat in DAOC, especially the pvp combat is far more engaging and fun. Yes, you have to target your enemy, but who cares? You are then responsible for positioning yourself, depending on what style you want to use, timing your reactionary styles, your style chains, etc.
Let me stress this again: Skyrim combat was a snorefest! Swing, backstep, swing, backstep, swing, backstep. Wow!!! Or if you are a mage: fireball, fireball, fireball, fireball. Wizardry in in the early 80's was far more engaging strategically.
Gimme a break.
