This is the first time I see this sector in the blockchain. I do not remember being done like before. The cloud player in the industry is not common in some countries at the moment. but it may become available if it grows in the future. in my opinion, it is likely to take an investment because it is the first in the field.

If their dev teams are able to solve the latency problem or at least reduce it considerably, I have no doubt they can reach new heights. Maybe even acquired by Sony

Latency is mostly closed by your computer and streaming server. It can be minimalized by better internet connection 

The problem is there is nothing you can do to increase your ping, if you have the best connection available but bad ping you're fucked .

Currently, there are not that many games on linux. But I think gaming on linux will grow in the future. It's very good that the devs are aware of this market.
