Splatoon released on a console suffering major droughts to an audience desperate for anything. It's no surprise that Splatoon was quickly bought up when there's nothing else competing for your money on the system.Splatoon is the most successful new console first party IP of this generation. So I don't think that you know what you're talking about. Also even with Wii U's bad sales, Nintendo first party offerings still outsells Sony's offerings. For most of the world, Nintendo's first party software > Sony's first party software.
Not sure where your second point comes from? Sony has never been big on it's first party games until recently, and games that are first party like Bloodborne have taken over the hardcore mindshare by storm. Seems like there's been a new Bloodborne thread on GAF every week since it released over a year ago. By "Sony", people refer to both its first and third party titles, the latter of which can be applied to non-exclusives as pretty much all of them develop for PS4 and XB1. Really, seems like you've sidestepped the point about the nostalgia and thus the purpose of this thread.
November is in summer? GB weather is weirder than I thought.
And dude, leave your console war nonsense out. Mario, Zelda, Donkey Kong and Co are far bigger IPs. More impact, more sales, more mindshare. Only thing eclipsing them is Pokemon.
Mentioning Crash, Spyro and GT also doesn't help your point. Crash got just a Collection announced, Spyro could only survive trough the juggernaut and Gran Turismo? They keep making new games of GT, or rehashing as you might call it.
I have no intention to bring up any fanboyism/a console war, but topics that involve any form of discussion regarding two rival console makers may be interpreted that way. See for example any Crash thread which invites trolls from both sides. Nobody is doubting the size of those franchises, although I wouldn't really put Zelda in the same bracket as Mario and Pokemon. Again, the purpose of the thread is about nostalgia. Those three I mentioned give nostalgia to many people, including myself.
Nobody is claiming GT doesn't suffer from rehashing, but let's not fool ourselves and say that Nintendo isn't one of the worst when it comes to repacking very similar experiences over a large time period.
