I would like to pick up a copy of the Gaming Quarterly #11 expansion.
Mostly because of the River end piece with a road! That would really help prevent some of the huge farms we are running into.
The other pieces look good as well. The more tiles, the better! Then again, we have only the first four expansions plus all the Minis and the Festival, so we are far from having every expansion.....
