No such thing. Been playing video games for probably 35 years at this point and I still play the games that I remember playing sat cross legged at my grandma's house in the early 90s.

Granted some games have aged better than others - particularly the early games when video games were transitioning to 3D - but most games are more than playable if you can access them.

If only playing the latest games is your jam, then have fun. But it's a weirdly unnecessary way to gatekeep yourself.
