I would say there's a ton of great games made >= 5 years ago, almost all still available, and cheap :)
CS 1.5, OpenTTD, AoE2, the likes..
Fancier graphics doesn't make games better. Gameplay, stories and jokes do.
Examples: Cyberpunk 2077 (Once all the bugs were worked out, I recognize it was dogshit on release), Baldur's Gate 3, Expedition 33. Would they be great games even with 15-year old graphical fidelity? Sure. But the stunning graphics definitely elevates the experience, especially in the case of Cyberpunk 2077. When you have the hardware to run everything maxed out, it's damn nearly photographic. It made me truly feel immersed in the game world in a way no other game has achieved, and I've played lots of VR games.
