The reason for the 2house restriction was that there was a distinct lack of good 2house games, and the results of the contest would fill the hole between 1house and 3house. I don't think there's as much of a lack of Martian Coasters games-- the winner of the summer contest is one, in fact. On the other hand, I can't think of any other particular hole that needs to be filled (at least not with respect to a Looney Labs product), so maybe that's not a worthwhile criterion for a design restriction. --dougorleans@xxxxxxxxx
