Hi! Yes, Au Contraire is much more of a social event than a retail event, and a couple of orders of magnitude smaller than Armageddon. There isn't much in the way of programming focusing specifically on anime or video games, but those media obviously include a lot of SF/F content, and there will be plenty of fans of both in attendance. Cosplay based on anime or games is very welcome, both casually and in the Masquerade. A couple of my personal favourite shows are Evangelion and Princess Tutu.
If anyone wants to run an anime and/or a video game panel, let us know; we could possibly still slot it in to the schedule.
