Or what if they prefer things other than playing video games? My buddy's sons really aren't into video games and he's one of those dudes who budgets to buy new games.
That is a very healthy way of thinking (though lets discuss again when they play Justin Bieber, romantic adventures themed VR game with tons of buyable accessories and asks you money to buy virtual Justin Bieber signed sneakers to impress some virtual girls)
Let them play them! My son has changed games many times. Sometimes he gets me into something I didn't like at first but I end up liking because we game together.
