It still blows my mind that one year ago today, we had no idea any of the following existed:
Astral Chain
Mario Maker 2
Link's Awakening remake
Tetris 99
Ringfit Adventure
Cadence of Hyrule
Ori and Cuphead on Switch
Official translation and release of original Trials of Mana
I have absolutely no idea how Nintendo/the Switch could follow up a set of surprises (and, just great ideas) like that. To me, that's the most exciting part of everything to come. Yeah when more Pikmin stuff and 3D World and Odyssey 2 show up it will be great, but to me what elevated 2019 to be a cut above other years wasn't Luigi and Fire Emblem, (regardless of how good they were), it was seeing Tetris 99, Cadence of Hyrule, Ringfit, etc. and realizing what incredible but completely out-of-the-blue ideas they all were.
