Might be just me, but playing Oblivion I never cared about my Stamina/fatigue, as I could do anything at 0 fatigue and it never felt like it had any noticeable effect. Being low on fatigue didn't stop me from running, jumping and attacking, and I never much cared for how it affected damage output as combat was just a case of swinging a sword and maybe some dodging of large weapons until I win.
In Skyrim I actually notice the bar because of the sprinting and how much a power attack takes off, and I actually have to worry about having enough Stamina to retreat.
In Morrowind I kind of noticed fatigue but still spent most of the game ignoring it.
Daggerfall was really the only TES game where I actually worried about my fatigue - it could kill me
