2017 was the best of these years, based on the strength of Breath of the Wild, Mario Odyssey, and Xenoblade Chronicles 2. The Switch's launch was a console launch of the style I never thought I would see again, in large part because the Switch needed to come out of the gate with guns blazing. 2017 was also the Western launch of Persona 5.
1994 was an incredible year on SNES (Super Metroid, FF6, DKC, plus a version of Mortal Kombat II that was as close as the 16-bit consoles could get to the arcade).
1998 was a strong year all around with Ocarina of Time, Xenogears, RE2, and Tekken 3 being my favorites of the year.
I'd also offer up 2006 (Twilight Princess, FFXII, Okami, and Wii Sports).
2013 (TLOU, Ni no Kuni, A Link Between Worlds, Fire Emblem Engage, Dragon's Crown, and many others). It was the first year in a long time where I was actually excited about games. Replaying Ni no Kuni now after having watched The Boy and the Heron.
