I like the new vault card addition. For me it gives structure, and goals which keeps me interested in playing and trying some new areas that I haven’t explored. One suggestion that I have is to make redeeming the vault keys more idiot proof. I accidentally unlocked an item that I didn’t want last night, dumb I know, but if there was one more prompt before committing to unlocking an item that wouldn’t have happened. I know that it is sometimes annoying having to click “do you really want to do whatever”, but if the vault card had this feature I would now have a few more keys to use on what I really wanted.
Let’s face it. You would have unlocked it eventually anyway.
