Hi Tintifax, Thanks for the kind words. I spent a lot of time (9 months) developing the base structure of this entire system. I'm an obsessive perfectionist, so it's technically as good as I could make it, and as usable as can be, given that the whole system was built for maximum flexibility. Room Creator isn't an 'instant' room, but it does give you endless possibilities to design your own room layout and position the doors, windows and other figures anywhere you want around the room. I can honestly say that since the original pack went on sale 4 months ago, I've received a lot of mail, ALL of which has been complimentary. So I must be doing something right. LOL. Xena, Yup! That's my evil plan! mac
