Leader Boards and stat tracking with friends was something I really thought would have made WS better.
Especially with all the Friend Code WC24 talk back in the early days.
I'm really hoping that Nintendo doesn't overlook online play & leaderboards this time around. The infrastructure is there, so its time for Nintendo to put more support behind their own features. If the point is to rope in the casuals and eventually turn them into gamers, well getting them online & competitive is the logical next step.
