I think golf needs a cultural shakeup at the highest level, because it has changed at the casual player level already - through observing my friends at least :)

Different games, perhaps some mobile apps for fun play, but more importantly for the Splinterlands ecosystem, all of the different support experiences that keep people engaged. I look at it a bit like "fan art" and covers that help people "own" their part of the game and also brings attention to the original.
