Does anyone else wish there was a hardcore mode I Skyrim? Super lethal weapons (for both the player and enemies) Needing to drink water and eat food as well as sleep. No fast travel. Individual damage to specific limbs (I'm actually incredibly surprised this isn't in the base game.)

I was amazed that New Vegas offered those features and Skyrim had nothing. Hardcore on NV is pretty popular, and online there are additional mods to make things even more balanced and realistic in terms of human needs porting over into the game. This is exactly why I always play as a vampyre in Skyrim. Even if it's blood you drink, at least it's something required regularly. My characters also sleep 5-8 hours a day, where as my buddy played 80 IG days and had them sleep once. I mean, seriously, your character should be dead or a dribbling idiot.

MORE INFO:

I haven't played NV on my laptop in a minute, but the mods I had made it so that I had to eat and drink regularly throughout the day and sleep every day. The former two were on a sliding scale, and since NV isn't riddled with filling/healthy food (the mod favours that), I found myself having to eat a ton of junk when pressed for options. Repercussions of not eating or drinking included lowered stamina, lowered strength with time, which all grew worse the longer I went until finally dying. Sleep was the most impressive though. Not sleeping would blur my vision similar to breaking your skull. Your accuracy, stamina, and strength would lower too. The amazing thing though, is that chewing tobacco or smoking (yeah, I got that mod) would help put off sleep, but usually lead to addictions. I also scaled the game so that my character was even with enemies. 

TLDR: The mods I added to NV made the Courier a chain smoking scavenger who takes even minor conflicts very seriously. I've never had to dedicate so much room to food, water, and cigarettes over weapons before.
