I tend to fight saving. I always try to avoid it as much as possible so...
I have auto save off except for sleeping, all the rest is manual.
No
quick saving either, not just because I see it as a bit of a cheat (imho), but also it can cause problems. First one is if you quick save in the middle of the action that can cause all kinds of bugginess and it`s very easy to accidentally quick save where you really didn`t want to and then you can ruin your game if you have no recent backups. manual save tends to make you think a moment longer whther it`s a good time to save or not and there`s less of a chance you`ll do it a crucially buggy point.
I tend to manually save before entering any main place like dungeons or cities and sometimes after long walks like 10-15 minutes, but not usually anywhere else.
