It's a hobby, and like any other hobby, it's profoundly stupid. How stupid is it to build model railways? How pointless is it to collect stamps. How dumb is it to fix cars? All "stupid" things we do for pleasure and for accomplishment. I suggest not being so focused on what should be stupid or not, and instead remember that time enjoyed is not time wasted.
I think that hobbies are ones where you're actually stretching your mind, even if they are "pointless". Building model railways and fixing cars can be fun and mentally stimulating for certain people.

There are a lot of very different kinds of video games out there, the variety is staggering. You have competitive games, which are in the same department as sports; you have complex creation games like Minecraft and Dwarf Fortress; you have virtual worlds like World of Warcraft where you can get immersed in the lore or tackle a difficult objective with other people; you have adventure games where you are taken through an interesting tale (ever played Siberia?). I could go on.
I think most people feel that they're wasting time while playing video games because there's a huge social stigma against them still, and because they're hard to connect to other peoples' experiences and expectations.
