What a great welcome!
Thanks to: Starwars 4J, mescheppers (the set costs $49.99), Bonaparte, Sinner, Batbrick, Vader, Copmike, freddy_LC, Asuka, Lieutenant Colonel Thok, DNL, Wout, iamded, Captain green hair, and of course Mr. Tiber (I've lurked enough to know NOT to call Mr. Tiber just Tiber--he'll keelhaul you for such an offense).
And hollisbrick, of course you're one of those great people. Unless, of course, you've gone over to the dark side (and by "dark side", I mean Megabloks)...
As for themes, I'm a castle guy at heart. That all started when I was a wee lad and I got the yellow castle for Christmas one year. Now that set got a lot of use :'-)
Pirates are also dear to my heart, although I could never bear to MOC the ships.
I have branched out--I have most of the Star Wars sets, all of the Vikings, most of the Batman and Spiderman, and a bunch of on-sale bargains from Adventurers to Avatar. Or should that be Avatar to Adventurers? Regardless, I've picked up quite a few sets over the years; even the odd train or two. I don't have any Bioncle, though.
Again, thank you for the warm reception!
