I see lot of problems and very few advantages. For online games you need super fast central server, which is the exact opposite of what the safenetwork is. Games are about appstores, centralized one. The bigger the app store, the more devs it has. Even Facebook failed misserably with trying to bring gaming to its platform. Devs re not interested if they do not get tons of free traffic from search. The whole industry stays on few big games earning fortunes and millions of devs earning close to nothing. People have very limited time, and games are like social networks, people pick the best and stay with them. So if you are not top 3 in the nieche, you are likely to fail. 99.999% of games does not convert. This means, if they pay advertizing, they do not tearn their money back. They pay advertizing to boost their app store positions, to get more free trafic. And then they can convert.
Decentralized gaming required different monetization aproach. We have seen a satoshi dice as a succesful example, that gambling can work. But for gaming, you need an app store, where all the devs come and are fighing for free installs. Or you need to implement a safecoin into economy, instead of typical virtual currencies. But that is also very iimiting. In freemium games, devs give users tons of free currency to keep them hooked. And they hope people get hooke and pay later. The amount of free coins pushed into system by devs is way larger than what people buy. So it is not possible to bring this model with safecoin. Devs need to create their own token, that they can print to infinity for free, and let people use that token in their games.
Of course, all those strategies can be modified, but in general without creating new monetization models, that artificially fit into safenetwork model we are not likely to see game devs jumping here.
The other issue is, devs are exensive. Game devleopment is costy. Devs do not develope without expecting huge profits. And without actual userbase it will be very hard to bring them here. But what we can see, is simply bringing existing web games, that does not require server and run offline in the browser. There are tons of such game hubs and for sure someone will bring them here. (If not owner, then someone will steal them and make them public.) So I think, there will be tons of web based stolen games, that people could play here without seeing ads or paying. I don’t like it, but this is the most likely scenario.
