I'd ask 'Switch 2', but frankly that seems a bit too far ahead.
Launch titles can make or break a system can they not (hello Breath of the Wild!), and I certainly like to think that Sony and Microsoft would know that. I suppose the obvious first guesses are LoU2 and Halo, but perhaps that isn't truely the case.
The Democratic Nintendo fan....is that a paradox? I'm fond of one of the more conservative companies in the industry, but I vote Liberally and view myself that way 90% of the time?
