This is it exactly.  I *get* pokemon, but not necessarily everything.  Digimon, for example, is still a mystery to me.  I might say something like, 'Wow, that seems pretty complicated.  I'm having trouble understanding which evolutions they can evolve into at any one time, are you sure there is a consistent logic?'  

But most adults would have already purchased the game so they would stop talking (*to them*) about it.  Parents, be sure your children's fantasy worlds have consistent logic, or we are all in for a heap of trouble when they grow up and run the government!

So great that you could be close with your brother!  Thanks for hosting great contests :)
