The only issue I would have with a 93 start date is it excludes games like Dune, Wolfenstein 3D, and the original Civilisation, which were earlier in the 90s.
Having said that, every cut off point has its flaws, and a more focused range could lead to a more focused and spirited community. Very weird that COD:MW2 is 14 years old btw.
Shooting out of a cannon with the wings hat and flying around in Mario 64 was such a pure fun experience for my kid brain. The switch in music and just soaring around a 3d level was really something special at the time.
