How I did it may not be the best. But damn, did I feel accomplished afterwards.
I went into DS1 without any background. I only looked up things when I was 100 % stuck (I played with the broken short sword for far too long). I definitely used some summons (mainly the NPC ones), but you could also choose not to.
Beating O&S the first time after a week or so of trying was one of the best feelings ever (don’t want to spoil anything hence the vagueness).
Elden Ring is definitely more beginner-friendly, but the sheer mechanics you can learn in DS1 will help in all soulsbourne games (maybe not Sekiro).
I have not played Demon souls, so maybe that’s a better jumping off point?
Agreed.
