Gaming, or anything for that matter, is childish if you approach it without restraint or standards.
Nothing is inherently childish, even playing with building blocks is an "adult" activity if those blocks create a sculpture, or become a wall. The same applies to games, if you approach games (video or not) the same way a child would, IE: without limiting the time you spend, or using it for a purpose such as a stress outlet, social tool, exercise, or for relaxation, and instead are playing for the sake of playing to waste time, or "because you have nothing better to do", then one might say that you, are indeed, childish.
I know it sounds dumb to say "gaming is serious stuff" but it has its uses and purposes just like any activity, and just like any activity it can become "childish" in the wrong hands.
