I do own this castle... Why... because I am a collector and no other reason. (Plus I got it cheap last year) This castle took POOPs to an all new level. Juniorized is exactly what I thought of this castle. The release of 6091/6098 caused me to continue my dark age that started with the fright knights. I can only condone this mess of a design for the (too few) parts and the awesome figs it contains. The unique pieces are nice to have for MOCing. As has been mentioned the sail, window, and roof bricks are nice. It also has some nice accessories for your figs.
What exactly is that siege thing anyway? I was thinking a cannon and that just turned me off even more.
The only thing I can't figure out is if this castle or Morcia is worse. I have both currently built in my garage sitting right next to one another. They just sit there taunting me... They are almost too ugly to take apart. It hurts my brain just to think about it, they are out there waiting for me...
