Video games are just video games. Anyone who judges people based on what video games they enjoy playing are people who's opinions that you shouldn't care about. I love playing the Souls games from From Software and I get confused by Minecraft. If anyone enjoys playing Minecraft that doesn't mean that they're "childish" anymore than me playing Dark Souls means that I'm snob who thinks other games are for casual players.
