But that's the thing, it doesn't need to be replicated.
I agree that this was an unforeseen runaway success for them, but it's not as if they need another Pokemon GO esque success to make them a continuous flow of money.
If they have a stable of titles that make them a few hundred thousand a day (which Pokemon GO may be able to do moving forward, even after the craze dies out) then why even bother with the console industry?
Because it leaves them in a position where they're depending on a fickle market that could turn on them at any moment. This is on top of the time it would take to reshuffle the company and get rid of no longer necessary parts of it. What if GO dies off as they're doing this and none of their other games are all that successful? There'd be no turning back. They'd be taking a huge risk in order to become a smaller company but with better profit margins. They'd end up like the rest eventually, having to just constantly spew out little games to collect scraps.
I don't understand why so many people feel that Nintendo needs to stick to a single business. It's just weird.
