Pes19, resident evil, silent hill, fortnite
Rainbow Six, Battlefield, punisher, mad max
Skyrim, Persona 5, Prey and Dishonored
GTA VC, San, 3, 5, tomb raider (2003), just c-st 1, crystal of time, wwe 2k 18. I play those game with my low ram PC (4gb) it seems not great
CS 1.6 ofc
Cave Story is definitely first, it's always fun.
Since everyone's posting several, I'd say the next ones in line would be The Legend of Zelda: The Minish Cap (and other zeldas but this one's my favorite), Paper Mario (the second one especially), Metroid (Prime and Fusion especially), Tales of Symphonia, Undertale, The Legend of Dragoon, BIT.TRIP RUNNER (the second one especially)... The list goes on. 
For me its Bioshock and Metro series.
It wolud be much harder for me to come up with a top 3 or top 5 list, because I've played so many great games that could compete for the positions from 2. to 5. ... but THE best ever? That's easy to answer:
Fallout 2
csgo,bf3,4,cod4,6.
Rainbow six,GTA,CS,CSGO.DBFZ
