I definitely enjoyed the multi-themed aspect of the tournament. It was probably the most unique type of tournament I've ever had the chance to handle in, and I'm really glad I did.
Admittedly, Round 3 gave me the most trouble, but I had fun with it. Like Jay said, it gives you the best view into the way your character thinks, and operates in the heat of the match. I found that very interesting, and appealing, although tough to find the right words to match my thoughts.
Rounds 1 and 2 were fun, too. Doing narrative RPing is something I enjoy, but don't have enough time for, as I take longer writing that way. It was nice having a sample of it, though.
I remember you commenting on Round 1 RPs being a little less stellar this year, Tom, and I'd agree with your explanation that, having seen from last year's ToC, people went in with more of a 'gameplan' than they may have for the first one.
Having had computer problems for a lot of last year, I happened to miss reading the 2006 ToC, so that's not really my excuse... heh...
Personally, I tried to pattern my RPs to be somewhat connected, so the first one was partly a lead-in to my 2nd. Maybe not the smartest idea, and I dunno if it came across as such [I'll find out soon! : p], but it is what it is.
Overall, I had a lot of fun with it. Thumbs up! ^_^
