Smash Ultimate would be eliminated by the same logic as Mario Kart 8 Deluxe, both are beefed up WiiU games. I know I've clocked a bunch of hours into Smash.
I would say Metroid is the winner but Tears is creeping up behind. Astral Chain looks good but I haven't played it. So does Xenoblade 3. Pikmin 4 is going to be a big one. For sure this thread will come alive late next year.
