I think the moon one has loads more potential if people pull their fingers out and get down to some hardcore building (unless you already moved onto another theme between then and now)
I finished my build, but people told me they were getting bored of the moon. It's a pity that it looks so unfinished (I blame the guy who came up with the canyon idea).
Hah, it would look worse without it methinks. I'll chip in finishing it if everyone else devotes 10 minutes to cleaning it up at the same time.
As for my opinion on the build, yeah, people are failing to keep interest. I myself have moved onto other projects leaving a rather large chunk of space taken up by that acid lab thing ( I'll do something about that if people want to continue). So yeah, I don't mind if you move on, it's got to the point where it's a bit too laggy to build anyways.
