Update Super Mario Party that'll make it better. It upsets me that Mario Tennis has been getting tons of updates while Party has got NOTHING, and Party sold so much better too. 6.4m for Party, 2.34m for Tennis and Tennis is the one getting all the support.
Super Mario Party is made by ND Cube while Mario Tennis is made by Camelot. You have to blame ND Cube, not Nintendo or Camelot.
OP: Friend messaging would be cool. Don't want to use a smartphone everytime for inviting friends. A browser would also be nice.
