I have no idea how much other paper mario have sold in the past and recently most nintendo IPs are selling much better than on previous gen. New IPs don't always do well but Sony new IPs have been doing great mostly. So it is really hard to know.
I'll just say that I'm looking forward to GoT and paper mario did never really caught my atention even though I saw friend playing it a few times.
