I'm just wondering if Skyrim is going to be the same as Morrowind where the more you run the more your stanima decreases. Or is it the same with Oblivion where running doesn't do this.

Not entirely sure, the only thing confirmed is that there is standard "Running" and "Sprinting", sprinting consumes stamina rapidly. Running probably stops it from regenerating, and walking/standing still causes it to fill again.

It was pretty universally despised, having your stamina deplete rapidly while just exploring. So I'm willing to be it's more Oblivion than Morrowind.

Oh ok, thats good. It was such a pain in Morrowind

I don't know, I kinda liked having the fatigue drain while running. Maybe it could happen slower, but still. I mean, you can just run forever without tiring, but if you swing your sword a couple of times suddenly you're tired?

I agree with this, honestly. Stamina ("fatigue" as Beth so ridiculously called it - glad they're finally fixing that) burns up a bit too fast in Morrowind, but it's ludicrous that it doesn't burn up at all when you're running in Oblivion. You could run literally forever and still have maximum stamina. That's just wrong. If we want to presume an astonishingly healthy person, then arguably it should take hours to use up the stamina, but there should be a limit somewhere.

And yeah - they treated it exactly the opposite in combat, which was just as ridiculous. I can run for 237 straight hours without losing any stamina, but I stop and take a single swing with a sword and a fourth of it vanishes instantly?

Balance, Beth.... balance....
