Best mindset to go into this with, to be honest. When I picked up Sword a few years back I thought the same and thought that even if it ended up being terrible, I'd probably be entertained by it for a while. In the end I was pleasantly surprised and actually ended up liking it quite a bit, despite all its flaws.
I might pick up Violet as well. I don't care too much about the exclusives given one can just trade them in but I think the box legendary in that one looks slightly less retarded at least.
