I didn't expect so many in 80s and early 90s. I can't go under 96-97 myself na mean

Edit: I forgot I played Full Throttle (1995) remastered this year but it was hardly remaster, I don't know why they even called it that.

Probably Punch Out for the NES. It was the 3DS virtual arcade version, though.

As far as the actual, physically old disc/hardware, probably The Maw on Xbox 360.

Super Mario 64 (1996)

If we're only talking games I had never played before this year probably Castlevania Symphony of the Night (1997).

The games on SNES Mini.

Final Fantasy VII

I played and completed Super Mario Bros. in preparation for Odyssey.
Man, have we come a long way.

Ultima-1981

高橋名人の冒険島 [Adventure Island] (1986). My GF got me to download it because it was her favourite growing up, and to my surprise it still holds up really well today. I had a lot of fun, it's probably my second-favourite 2D platformer now, just behind SMB3. Sad that it failed in the West, but with a boring title like that one can understand why.

Final Fantasy V, the original 1992 game.

Legend of Zelda, Link's Awakening on my GBA SP.
