I'm very intrigued by this. I think it starts to set the tone for more "playable" modular buildings really.
I like Wodanis' thought here -- If you're not into play, but like the look... there are other ways to work it into your modular city. You need something to look over to see your city.
I concur with meyerc13 on price point. Honestly, this doesn't look like a 1000 part set.
Have to give TLG some credit --- they're looking for ways to take what excites the fans in its multiple theme lines as well as people who just want a great parts pack and continuing to find ways to deliver and build exciting new product ideas.
