There are a lot of initiatives that are moving in that area. Sure, Holozing is one. I do not follow it closely so I cannot comment on the game or prospects for success. @simplegame is building an entire Web 3.0 platform that has potential. There is the latest spend2earn with an app evidently built to help that initiative. There is the lightning network integration.
These are just a few off the top of my head that appeared in the last few months.
