Does anyone know of a mod that effects your fatigue to make you tire after running a certain amount of time, the fact I can actually run the entire Mojave without even having to catch a breath annoys me, so if anyone knows of one...please do share it's location

This is part of what my Encumbrance Module does (which is part of my Realism Tweaks). I haven't ported this module over to my NV Tweaks yet, as I'm currently working on my Hard-Core Module (while completing a Major update to my FO3 Tweaks). It should be done in a few weeks.

My NV Realism Tweaks currently only uses Fatigue damage as part of my optional Weapon Effects (along with a Fatigue display).

Ahh right OK, then patience is a virtue
