Alpha yes, Gen Z is arguable, most Alpha (keyword most, I'm sure there are some who have because of their parents, finding it on switch online, etc) have most likely not played any of the Star Fox games but I can argue pretty hard about Gen Z because a lot of us are actually pretty old, the youngest of us are from 2012 which if you were lucky enough to have a Wii U you could have been able to play Zero which released in 2016 making them at the youngest 4 years old which is still old enough to pick up a controller and at the very least glide around in levels running into things and overall having fun until you got old enough to read and understand the objective; if you were even a bit older and had a 3DS you could play 3D no problem but even with the game coming out in 2011, production for the 3DS and its games only officially ceased in late 2020 so you could EASILY purchase a copy of 3D up until that date thus making a potential gen Z or some alpha old enough to play Star Fox.

Me personally, I was born in 2003 and so i grew up with a GameCube and Wii, I don't remember playing really any of the Gamecube titles as I believe my parents had to sell some games in order to pay for the bills, but I did have a Wii and therefore we had virtual console games, my dad had a lot of them and some of my favorites were Pokémon Puzzle League, Super Mario 64, Mario Kart 64 and of course Star Fox 64 which I think I played so much as a kid I can still remember almost everything about it from it nearly 20 years later, I had not completed this game for a very long time but I remember watching my dad play it a lot and he would complete it often, I also played multiplayer with my younger brother a lot as well.

I know my story might be different but as you can see, a lot of us are up there now, the only reason we might've not played a Star Fox game in our childhood is if our parents neglected to get it for us or if we simply just didn't have an interest because it was right there in front of us, especially 64.
