Snowflakian, I love your idea of inter-connecting playsets and rooms. I think that would be the best thing to happen to action figures in a long, long time. I don't, however, think that having to buy multiple build-a-sets would work. The fans would eat it up of course, but having to buy all the different sets to complete a building would be a hassle. I would love the sets interconnecting, but not necessarily be part of the same playset.

For example, you could have an underground sewer/tunnels playset and have another building interior that could stack on top. Or another building type, warehouse, that could connect to the side of the previous building. You could construct and build your world any way you see fit. And you wouldn't have to buy every single piece to complete a building or playset. Most of us would buy them all, but you wouldn't have to.
