So like the traditional video game market?
I'll take your word on it.
It's a lot faster to drop a mobile game for most- they're generally free and as easy as deleting and installing the next one when you become bored. Traditional gaming tries to keep you invested longer, and costs more, microtransactions from mobile not included.
So no, I don't see them being the same, but I can see what you're getting at; it's similar in a broad sense, but the "mechanics" of mobile vs traditional are pretty different IMO.
To the broader point, I'm not sure less invested people really follow game companies, so much as franchises anyways. King in name probably doesn't have nearly the "pull" as Candy Crush itself does; Activision likely isn't as cared for in name by the general population as "Call of Duty" or "Skylanders" either.
It'll be interesting for sure to see how this all pans out though, it's not like Activision are business-stupid or something. They must have a calculated reason for doing this.
