I have also been playing RDR2 on and off, and am on chapter 4. I am slowly trying to finish it but I can only take it in small doses. While it used to be a beautiful game before Ambient Occlusion got removed via patch recently, gameplay wise it is the most overrated and average experience I have played in a long time. I find myself having trouble getting motivated to play it at times.

Sekiro: Shadows Die Twice will probably be my next finished game. Started it this morning, already in love with it, and I understand it's not too long.

Then Red Dead Redemption 2: Epilogue (Beat the main campaign, not the epilogue.)

Wait, if we're talking about like, old ROMS and stuff then add:

Donkey Kong Country
Donkey Kong Country 2: Diddy's Kong Quest
Donkey Kong Country 3: Dixie Kong's Double Trouble
Super Mario World
Super Mario RPG: Legend of the Seven Stars
The Legend of Zelda: A Link to the Past
Mega Man X
Mega Man X2
Mega Man X3

I tend to cycle through all of those and occasionally Final Fantasy VI at least once a year/every few months. That's my list of top favourite SNES games so I return to them occasionally. Super Mario World, MegamanX/DKC trilogies once every few months or so, with Zelda, Mario RPG twice a year with Final Fantast VI once a year or two (it's a pretty damn long game compared to the others so I don't return to it as often despite it being my favourite game ever.)

I also return to Bloodborne, Dark Souls III, and Skyrim at least once a year, oftentimes to play with friends.
