I search every container.
I hoard every usable items and never use any of them.
I talk to everyone.
In short, I have severe rpg playing symptoms
I do the same.
I also do save scumming.
I don't think anyone plays slower than I do.
In this game resting has no downside, so I have no problems with getting injured or using all spells in a fight.
In Kingmaker I even reloaded when I took much damage in a fight and I save scummed healing spells or potions. I cast spells only when needed. The time limit made me paranoid.
In NWN2 there were persistent spells and in WotR are epic feats that buffs last 24h. This helps me a lot because then I use buffs more often.
