Marvel vs. Capcom: Infinite Is coming out 2017! No Wolverine, no X-men of any kind is the rumour due to the Fox/Marvel Studios thing. Too bad, Wolverine was always integral to the series. No surprise that Captain Marvel will be front and centre, what with the movie coming out.
Stadium Events and Duck Tales did hit well over $30k before, but Super Mario Bros hitting so high is odd because it's not a remotely rare game, even if it is tougher to find in gem mint condition.
SF 30th Anniversary Collection! The real gem for me is the original Street Fighter. I don't think I've play that since the early '90s/late '80s in the arcade.
"The Collection, due out May 2018 for PC, PlayStation 4, Xbox One and Nintendo Switch, includes 12 fighting games. They are:
