I think my favorite part was where I got engaged live in front of a couple hundred members of the fandom where I met my fiancee - definitely a highlight for me!
Other than that, it was great to meet a bunch of people I've only ever met before online. The cosplays were amazing all around, the gathering of the Jades was fun, and there were exactly 8 Serkets (including my now-fiancee).
Ender and co did an amazing job of putting this together and running it, and I'm so glad I was able to defeat Delta Airlines in ritual combat so I could make it!
Did Friendsim 2, among other things
