Just looking at this is exhausting. It is why I only recently finished the main story of POE1 despite being a kickstarter backer. I can't deal with it.
I don't know if it's normal or if it's related to my being on the autism spectrum, which I didn't know about until my son was diagnosed. Some of what I've learned concerns difficulty with processing information and dealing with too many tasks or too many choices.
So part of me thinks it might be just me, but another part of me looks at this and says it's ridiculous; that of course it should be better organized. There are even White March quests here that say nothing at all about where they take place.
I don't know how Obsidian wants to organize it. I would really appreciate it if companion quests had their own list. Sort by level? By area it was obtained? By area of the next step in the objectives? I don't think the actual game designers need my help.
