Liking games is a good reason to go to a gaming convention, though not required.
Back in the day, the ‘coolest’ game was the Pokemon Trading Card Game (which is pretty much a simplified version of Magic). I played a lot of it, so much that me, my husband-to-be, and my friend would have our parents take us to the Toys-R-Us to play in the Pokemon League. We did that for quite some time until the store discontinued the Pokemon League for the Yu-Gi-Oh card game league. I never got into Yu-Gi-Oh, so it was rather sad that there was no more Pokemon there.
I tell you this just in case you’re wondering why Yu-Gi-Oh is branded as evil in this comic. >_>
