In Skyrim, I feel the same is true. The addition of a "hardcoe Mode" (does not necessarily need to be called that) to the Elder Scrolls world would extend the life of the game dramatically. However, since it has never been included before, the details of such a system are still completely up in the air. So, I'm curious: if you could design an ideal "hardcoe Mode" (name and all) for Skyrim, what would it consist of?
My ideal hardcoe Mode would have the following restrictions:
- Sleep is required for survival. Go too long without it, and I'll pass out from exhaustion or die.
- No fast travelling. If I want to get somewhere, I'll have to hoof it or acquire a mount. Also, since sleep is necessary, I'd need to map out my trip so I can stop at a campsite along the way, or bring a bedroll. Abandoned campsites around Skyrim would now be worth adding to my map, as they'd be necessary stops on long trips and good places to store emergency items.
- Speaking of the map: initially, the only locations that should appear on my map are major cities and locations in my line of sight. All others don't appear. Also, locations in my line of sight do NOT get automatically added to my map - I have to open the map, select the location, and pick "mark on map" or "add to map" in order for it to remain a persistent location. Otherwise, it disappears from my map as soon as I can't see the location anymore.
- Nonstop world. When I'm picking a lock, searching a chest, or browsing my inventory, the world is still alive. I can still be attacked and killed.
- Realistic encumbrance. Why am I able to carry five shields, a sword, an axe, and three hundred garlic on my person? If I want to transport lots of items (for trading, perhaps) I'll have to use my mount. Otherwise, I'm limited to what could fit on my body, in my sheathe, or in various pockets and satchels around my waist. Collections of weapons and armor would now actually be impressive feats. Also, gold would encumber me, but only if gold could be transferred in and out of a bank or other secure container - that way I could only carry the gold I'd need for whatever it is I'm doing, and leave the rest safely stashed away in a bank or personal chest or what have you.
- Realistic skill building. In the real world, many skills require years of learning under a teacher before you can become adept with them, and even then Mastery is years more away. Why then can I seemingly self-teach armor and weapon repair up to Mastery level? In hardcoe Mode, all skills take 2x longer to build, and Master trainers would be required to climb any higher than 75 in most (or all) skills.
- Balanced magic and enchanting. Magic is an area where it's hard to be "realistic", but, regardless, we can draw from common sense to come up with some interesting restrictions. For example, you cannot enchant items or create spells until you are 75 or higher in the school of magic you wish to use. Any enchantments you place on an item are limited by the size of said item - so rings may only be able to fortify a skill 3pts, while a cuirass could hold an enchantment of fortify skill 7 or 8pts. And magicka recharge rates are reduced, maybe even halved.
- Realistic economy. I want to see some economic improvements in Skyrim outside of a hardcoe Mode, but there's still some interesting ways to add realism. For example, price fluctuation based on outside conditions - e.g. some items are worth more in certain areas, and to certain people, than they are others. So in order to get the most value out of an item, I'd have to determine 1) who will pay me the most for it and 2) if the difference is worth the trip (remember how dangerous long trips would be) before selling. Anything that can kill someone with any sort of efficiency (spells, weapons, bows) should be costly. That way I'll focus on using the things I have and only upgrading when I can afford it. Also, the price curve overall should be steeper, so that things start out at the same base price, but become more expensive more quickly as you move into the higher tiered version of those items.
- The cold should be your enemy. There should be clothes that keep you warm that you can wear, trading protection in battle for protection from the elements. Certain regions should be safe to stay in (valleys) while others should be inhospitable without the right gear and proper planning (mountainous areas). Altitude should be a factor, as should the weather and time of day.
I'll edit with more as I come up with them. In the meantime, what would you like to see?
