I think I've exceeded my yearly dose of: cosplayers, furries, bronies, anime, manhwa, yaoi and all types of loud-cheerful-teenagers. This does not mean that I hate those things, but like the title says: too much is too much.
And I only went to the anime/scificonvention to hear Sandy Petersen talk about Cthulhu and horror in role playing in general.
Unfortunately I have to go back tomorrow for my own panel. (Sword fighting IN SPACE!)
On the positive side:
+Sandy Petersen is awesome.
+Some of the cosplayers really do have nice asses costumes.
+Derpy hooves costume was cute.
+Dr who seems to be popular so I still have some faith in Finlands' teens.
+The Romantically apocalyptic duo had awesome costumes. (And it is nice to see that people cosplay more than just the top10 most popular animes.)
