We’re mostly intrigued with 1:1 locomotion and agility in competitive multiplayer. For instance players who can run a marathon, or throw a baseball, will have a distinct competitive advantage over players who cannot. But, in theory, if you played enough it would supplement physical training.
For the casual gamer it may not be interesting, though that depends on the learning curve - eg regular sports can be pretty challenging and physically exhausting, yet people play them casually.
But in particular competitive gaming and esports would get a lot more interesting this way.
But moon jumping would be a fun game concept :)
