Hey, I was at Metrocon in 2006, too!
Good con. I went a few times, probably one of the best Anime conventions ever. It wasn't so big that you couldn't do -everything-, but it wasn't so small that there was nothing to do. The amount of people who show is just right for a large party, but it doesn't feel so much like a mob as larger cons do. Also, the nicest group of gamers I've ever met at a con. Gamers that go to anime cons are usually such sucktacular people. It's weird.
Also, the big 'event' of Metrocon, the human chess match, has always been really fun for an amateur production. It was enough of a highlight that I went back to the con for a total of 3 times.
If I was in the states, I'd totally go again.
