I think overall Souls games have amazing design, but there are also some parts which are very, very lacklusting. For example, any kind of platforming has no place in these games with how poorly the character controls. I also don't like that not all builds are viable, like when I make a parry-centric build and then half of the enemies and bosses can't be parried just because. But to me, the worst of all is the esoteric quest, item and hidden mechanic design and conveyance. It's absolutely impossible to complete 50% of the quests of any Souls game without a guide. You have NPCs popping in different places of the map randomly, but it you picked a flower in the main path then the NPC will disappear forever and the quest will fail. It's like in Bayonetta 1 where you have to advance to trigger a hidden mission at the start of the level, but if you go forward 2 steps instead of one then a cutscene triggers and you can't go back to the start of the level anymore. Same with the items, with designs that give you no clue to their utility and descriptions that are functionally useless: "Kiss the finger to unfurl your clairvoyance". Even after using the item you won't be able to understand what it does most of the times. Or the icons that pop over your health bar that are impossible to interpret. The UI overall is shit.
