All things considered Nintendo did a lot of things right software wise this past generation:
-Turned Luigi's Mansion into a tier 2 franchise (5 million + copies sold)
-Created a new popular franchise with Splatoon that has the potential to become one of their heavy hitters
-Made Fire Emblem a viable series
-Gave Zelda a second youth with BotW and made it an industry leading franchise again
Now if only they could salvage Metroid...
Also:
-Reestablished Animal Crossing as a top-shelf franchise after the series faltered on the Wii
-Kept Mario Kart and Smash buzz going with solid entries that sold well relative to their consoles and put them in a position to do well on Switch
-Gave Pokemon a second wind with Go and Sun/Moon, not that it was ever weak
Real shame about Metroid and Mario RPGs though. Seriously, those sting.
