This is a case where 'always running' feels like a sick joke. The movement speed is far too slow, it never feels like you're 'running' and your only option is to move slower by holding down shift.

I used the G.E.C.K. within 2 hours of playing and raised the fMoveSpeedBase from 77.0 to 88.0, and raised the movespeed bonus when your weapon is put away (fMoveSpeedNoEquip?? or something) from 1.10 (10% bonus) to 1.30 (30% bonus) so now when you put your weapon away you sorta feel like you're "running", and you pull out your weapon and stop "running" for combat. I now find the game IMMENSELY enjoyable.

I cannot recommend enough that bethesda take these changes and MAKE THEM VANILLA!!!!

surely in a post nuclear wasteland where we are under fed and subject to radiation we arent suppoed to be moving like olympic athletes ?
