Played around with Survival Mode on PS4 today.
I don't want to start a new game. Although I'm tempted, would be nice to start with nothing and your prime objectives being realistic, as in find shelter, food, water etc. in a wasteland.
At launch I was disappointed that the original mode was not like in NV, but in hindsight I think I would not want to play the actual game like this. I'm too much of a completionist and therefore want to loot everything, do all the quest etc. Survival mode would make that playstyle a chore and not fun (I also play on hard and not higher, overleveled and over-geared myself as I prefer humans to die in just a few shots etc.). Not to mention the lack of quicksaving just to try things.
So, coming to terms with that realization, I will prepare my latest savegame (Platinum trophy) with my grizzled, overloaded character to manually adjust Survival Mode. I finished the game with the Institute (+Minutemen) and did a lot but there are still major locations on the map that I haven't visited yet + all the DLC (also I'm still just lv66 and want certain perks).
Before starting Survival mode seriously, I'll prepare my settlements. Add maybe one or two more for strategic saving and populate the currently empty ones. This could take a while as I checked all the new settlement stuff and I might want to get funky during customization...
But mainly I want to distribute storage containers with food, raw materials and ammunition. I'm not sure if they changed settlers stealing all this stuff from your work bench otherwise, either way, could be neat to have different stuff available in each settlement.
Maybe I'll choose one central, big base for my main operations where I can still have the luxury to build things in peace.
I also don't want to have my current tons of supplies available everywhere as that would kinda defeat the point.
Due to lack of fast traveling I'll make my character equipment leaner as well, but I won't ditch my good gear or weapons.
I'll spend a day in the settlement to get a feel for how much supplies I need and create a stock of the new medicine items.
Minor things:
Stimpaks dehydrate your character and are basically worse than food+water so I guess they are now just for healing crippled limbs? I'll have to look more into cooking etc. Probably also distribute my Nuka cola collection as the caffeine allows you to postpone sleeping.
PS4 Rest mode + ability to teleport to the Institute should also make up a bit for the lack of saving (but boy will dying suck now).
