A situation where you can basically earn real money to play games is a good one. If an IP / Studio basically tokenized their in-game currency, that would be cool. It's pay to win, but the players are the ones getting paid.
Legality is a non issue. Companies need to go to where laws are favorable, and everyone else can do everything under the table. Local laws will adapt, simply because they need to. We have the right to create opt-in micro economies amongst eachother.

Idk about Nimesis yet, but social media with tokens is one of my favorite ideas for many reasons. Like Steem.
As of now content creators on youtube for example get paid by ads and Patreon. What if their Likes were tokenized and they could get paid that way?
There has yet to be a solid implementation for it, but that kind of system has so much going for it. It's only a matter of time until someone does it right.
