The biggest concern is going to be internet availability and data caps. I tried the beta for Project Stream (now Stadia) this past winter. It worked well and was impressive, but I have a good internet connection with a 1TB cap. I have friends with much worse speeds and harsher caps and I am not sure if this would be viable for them.
I am more concerned about 'physical' gaming being phased out. I doubt Stadia will do this soon, but I like building a new computer every 4 years for playing games. Maybes it's something I won't actually miss(like how I don't miss CDs for music), but it remains to be seen.
Is the grind a way to slow progression in order to make micro-payments more desirable? Fuck. That.
I really enjoyed it for the first 20 hours or so.
Also, it doesn't have that high of a playerbase.
The trap that you should avoid falling into is assuming that's the only way games can thrive. F2P games are huge and dominate the conversation, but I think indie games are the best they have ever been. My favorite game last year was Into The Breach, and by all accounts it sold well in the same market that Fortnite dominated in.
Games are evolving in weird ways, but it's in a multifacted and diverse way.
It is kind of another beast altogether for Google, Shadow, Microsoft (xCloud), etc. to dedicate actual hardware for your usage. Shadow and others like it are essentially remote VM w/ GPU that you rent by the hour. Stadia, xCloud, etc. we don't know what the business model is going to look like. The only positive here is that Microsoft, Google, and Amazon are all cloud infrastructure companies so in theory, they could price their offerings cheaper than a company that is a tenant on their systems.
Microsoft has made clear that they want Xbox to be a platform independent of the physical box they sell to people. They are 100% going in the direction of Stadia. The big question is how they are going to do it in regards to their next console.
That would be considered unfair competition and they would probably be fined by EU, I guess
The vast majority of your support department can be let go.
