> When your grandkids ask you what you did with your finite time, is "I pwned noobs" the answer you want to give?
You are being ridiculous. First, unless the person was a professional gamer they would probably answer with the time they spend at work and time time they spend raising their family. But let's assume the grandkids specifically asked what they did for entertainment.
The answer would then be something like "I got together with my friends and we played the popular online games together". They would probably also mention any other things they did a lot of entertainment, too.
