I'm adding Metal Eden and Daemon X Machina Titanic Scion. Raidou is in there as well. 

Updated to this point. Keep 'em coming!

Expedition 33!

Expedition 33 and DK Bananza. Probably Hades II.

If we're counting rereleases Capcom fighting collection 2.

I'll add another vote for Silksong.

To update my prior list again, I've gotta Hades II since I've added that to my personal list of GOTY considerations.

Updated to this point! Thanks for all your contributions so far.

Absolum is so fantastic!!!! With Ninja Gaiden 4 quickly on the horizon, don’t know if it’ll stay there, but Absolum has quickly become my GOTY

I totally forgot to add Shujinkou!

Shujinkou (NS)
A unique turn-based RPG with lovable characters, addictive dungeon-crawling gameplay, meaningful side-quests, great music, and inventive syllable-based fighting mechanics
Score: 8/10

Kirby Air Riders definitely deserves some recognition here. One of my favorite releases this year! Second only to MKWorld for my personal GotY (though it could push ahead).
