For me it's GTA San Andreas because of CJ, that game is amazing
I have very fond memories of playing through Doom2 and Wolfenstein 3d with my Nan.
At 60 years old she still loved playing 1st person shooters. What a champ.
As the technology got better (ie, Doom 3) where aiming was a thing she struggled to play but still tried and loved it.
I remember the games not because they were great but because of the time I could spend with my Nan on our hobbies.
Nan was the best.
