Interesting I shall try this sometime. I definately have played hardcore on Fallout - New Vegas (Hardcore/Hard with Project Nevada and FOOK) although I fast traveled - Skyrim legendary is okay once you get to round level 10, untill then it is stupid hard. I've been going for a vanilla experience recently, the only gameplay changing mods are SkyUI (if that counts), weightless potions/food (I found managing them to be unappealing), and the unofficial patches to avoid gamebreaking bugs.
