Oh the potential is huge when you combine it with BAT, not just for players but those who watch livestreams too. There will be literally rewards for everything and when you combine all those things you mentioned, there's no reason why gaming companies can't benefit as much as the players they want to keep playing their games as well with the rewards pool factored in for posting content related to the game.
This potential reminds me a bit of what happened when mobile phone companies had control over the people with their pay as you go and monthly contracts. People were getting shafted. But then smart phones came out and turned the industry on its head as it then became about the phone, not about the phone company supplying the contracts.
Something similar is happening where we will start seeing more of these games, crypto based services and products coming to the fray where every one (consumer and business) will be sharing rewards and tokens without the need to farm and sell off data like "you know who".
It's exciting!
