Not to mention more access, period! Anyone can play competitive Tetris on a variety of affordable consoles or computers, but if you really want to be a world-class competitor at the old classic arcade games, then you need the space and disposable income to purchase said games.
I really enjoyed The King of Kong documentary and rooted for the hero dad of the film who was going up against the reigning champions, but I’ve got no doubt they would have all been put to shame by much younger competitors if this was a more affordable hobby to get into.
