Hopefully Nintendo will learn from the mistakes of 2018 and in future years focus more on a steady cadence of new core games throughout the year as they did in 2017 to great effect. They got lazy and arrogant this year and thought they could cruise to 20 million by relying mostly on old ports and B/C tier games while going 13 long months without a proper system seller. They'd better not make that mistake again.
Who knows, maybe it let them know they can have solid sales with just a handful of small-medium sized hits in the first 45 weeks.
Games that had debuts over 100k. Kirby: Star Allies, Mario Tennis Aces, Octopath Traveler, Super Mario Party
Games that had debuts over 50k. Mario Rabbids, Labo Variety, DKC: Tropical Freeze, Minecraft, Taiko no Tatsujin
Games that had debuts over 25k. Dragon Quest Builders, Snack World, Labo Robot, Captain Toad, Pro Baseball Famista
If that lineup can make a $300 console maintain a steady 40-50k weekly baseline than why bother with mega sellers throughout the year?
