Experience Settings - I'll keep 0 Slowest. If I understand correctly I could add Arwen's Arwen _Reduced_XPR to slow it down even further?
That's pretty extreme to be honest
Will take you very long to reach a high level, but up to you!
Sneak - I used Vanilla Very Easy, but at higher Sneak levels I understand why there are optional settings on it. I'm torn between Easy and Moderate. Any views on which setting that is both more "realistic" and still fun?
I personally prefer moderate. Sneaking is a bit more difficult, but you dont pull the entire building if you eff up.
Global Damage - I used 2.0x FWE default and liked it a lot. I'm considering lower it to 1.5x, though. At least on higher levels when good at sneaking this should actually make the game a bit more challenging I guess, plus getting hit won't be quite as unforgiving. Does someone play on 1,5x?
I play with 1.25(I use the Alternate FWE preset to be precise). I like the lower settings a bit more because it makes enemies like Enclave and Super Muties far more durable.
Also, I'd like to add Primary Needs but with rather "easy" settings. Any tips on how to set it up to have hunger and thirst as factors, but not having to micromanage too much (i.e. bringing cooking equipment and what not).
Well it's simple enough to change, all you need to do is lower the food/drink/sleep factors in the PN menu. But just so you know, we already reduced the dafault values quite a lot in 5.x
You'll only get those values if you start a new game or reset PN though. If you used a save from 4.x or before you'll have to manually reset PN to get the new rates.
