Work in progress, but off the top of my head:

Shadow of the Colossus
Outer Wilds + Echoes of The Eye DLC [NOT The Outer Worlds]
Suikoden 1 [NOT 2, but 2 is really good]
Return of The Obra Dinn
Windjammers
Power Stone
X-Men vs Street Fighter
Final Fantasy VII
Maniac Mansion
Bioshock

I'm almost positive not a single person other than myself will ever see this, but I think it's best to expand lists like this to a top 25 at this point. There are tens of thousands of games spanning a growing list of genres. There are too many great games competing for X slot so I'll be adding to this list soon.
