To be honest, it's all about microtransactions these days with games.
Gone are the days where you would buy a game complete! Remember those? Looking at you 1990s-2000s!
Fortnight BR changed the scene a lot last year, you give away the game for free and then give a shit load of customisable skins, weapons, items and the like. Millions of micro transactions and they overtook revenue of call of duty in the blink of an eye.
So that's where a potential lies with creating a game and make people want to buy customisable things with micro transactions. The card games are a great start but I must confess, have never played them on steem and I haven't gamed for a few years.
However, seeing how things have changed, flash games like candy crush asking to refer friends to continue instantly or wait a week to unlock other levels... You only have to look at previous successful companies /games to see the principle and then apply the payment system to steem.
(I am sure the technical side is a lot harder in practice but these are the theories I have about it - gaming is for sure another ribbon that can be added to the bow here)
I'll stop rambling now!
Hehe was a good ramble and yeah, I can't wait for games like that which at the same time figure out a great way to integrate it to Steem and everything they offer combined with something like BAT to make it more "worth it" for players. Being able to earn even something by playing games, creating content about it will be a good combo with the rewardpool and adrevenue sharing to take care of both marketing and not leave players feel empty at the end of the day if they decide to play something too much and have nothing to show for it like current centralized games do.
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!
