Would it be possible to make a fast travel mod that would only allow you to fast travel after you have slept in a bed for 8 or more hours and then once you use the fast travel you can't use it again till you have slept for 8 or more hours in a bed? It wouldn't work with waiting for 8 hours you would have to actually sleep in a bed for it to reset and be usable
Would be nice to cut down on fast travel usage but not take it out all together and make it not so much of a cheat ( that's how I look at it :) --- "After 6 years on gamefaqs, one thing that I have learned is to pay little attention to the opinions or statements of new users." -aiRWaLKRe
I'm sure something to the extent of it would be possible, for example only being able to fast travel if you have the well rested buff. I can't say whether or not if it could be given a set time to work but using something like well rested would be as simple as copy pasting variables around.
