Non Existing Video Games You Would Love To Have

[Proton]

A Mario skateboarding game, old school Tony Hawk-ish.

no more mario <sport> games please.

But how else will we have sports games that have actually interesting and fun gameplay elements beyond just "this is the sport"?

Why.
That's what sports game fans have wanted from sports games since the 80s.

The appeal of sports game is "this is the sport."
The companies push realism in the gameplay because that was always part of the appeal of sports games.

No one's ever going greenlight arcadey sports games anymore without a big name like Mario to sell it.

There are multiple "arcade-y" sports games that have nothing to do with Mario, and sometimes are better than Mario ones.
