I only played Doom 1 and 2 when D3 was about to come out, so it was about 10 years old. I played some mod with polygonal models/hires textures so it wasn’t a vanilla experience, but in terms of game and level design I was quite blown away.
Also I played Metal Gear Solid 3 only about 5 years ago, so that was a ~15 years old game.
