Sounds like a lot of fun! I've always wanted to go to a convention like that but never got the chance really. In truth, I've never really been around cosplay, but it seems like fun for those involved; I'd probably never do it though… That's good to hear about Mr. Iwata, he was such a great man, and he very much will be missed. If I ever had kids, I'd make sure they knew how to maintain the gaming equipment in games. It's sad when kids don't know how to do that kind of stuff. They can't help it though. I wish you had some photos too, I'd like to see how it all looked.
I'm glad you had a fun time and thank you very much for sharing!
