FFVII Remake
Persona 5 Royal is absolutely brilliant too, they're pretty much neck and neck but VII Remake was a fantastic experience. Streets of Rage 4 is closely behind those, just for being so well crafted. Dunno if I'd count Xenoblade but it's up there.
New Horizons would be up there if it weren't for a few baffling user experience problems and poor pacing (I paid off my loan and completed the fossil collection faster than ever).
The only games I could see dethroning FFVII Remake for me in the next 6 months are Yakuza Like a Dragon, Tales or Arise, or something we haven't seen from next gen yet.
