i haven't played vanilla in a very long time but everytime i play through sotfs there are so many areas which exist just to piss me off, gank fests of loads of high agro range enemies which leaves me just clearing the area out permanently to get through it properly.
Thing is in my vague memory of vanilla I don't remember any such area causing me much aggravation. I actually remember the game being pretty easy.
Ended up buying vanilla just so I can see if sotfs is actually just designed by a crazy person because the game just feels like a slog to play between eathen peak and iron keep. I'm struggling to think what part of sotfs is actually an improvement.
it's widely agreed upon in my circles that scholar has better item placement but original has better enemy placement, meaning the ideal would be a hypothetical fusion of the two.
i normally just go with scholar for my playthroughs
