It is worthless only to those who cannot find worth in it. You heard Wayne's example...

Besides: it's all in fun! Yes, kids can get into it too much, but that can happen with everything. A lot of sugar is bad for you...is sugar worthless? No, because plenty of people eat it now and then and enjoy it. We all have hobbies and ways of relaxing outside of work (even workaholics do)...it's over-use thats bad, in my opinion.
