Is there any way you can see a history of what you have spent FATE/NEX on?
I’ve had a quick look around and I can’t see anything resembling such a thing. So I am assuming there isn’t one but I thought just before I completely give up I’ll ask around and see if perhaps I am missing something obvious.
Unfortunately there’s no handy list of every Nex-locked option you’ve taken. A lot of the Fate-locked stories will give you qualities to signify that you’ve unlocked it and quantify where you are in the story, and of course if you purchase items those will be in your inventory. For the other stuff you just have to rely on your memory and/or your journal to keep track of what you have and haven’t done.
