I'm fine with the sizes of most of the worlds we've been getting lately. Every world in my game has a specific theme, which may or may not correspond to what the developers originally had in mind, and with ten or more lots, I usually have enough space for both a community and places to go. Henford-on-Bagley will be no different, and since I'm probably not going to have more than six farmer families, twice as many lots sound great to me. The worst an EP can be is a shallow beauty, nice to look at, but lacking gameplay-wise. I'd rather have it the other way around, if I can't have both.
That said, I still think the official excuse for the small sizes of the worlds is silly, but who knows, this is a farming world, so maybe at least the lots themselves and their surrounding neighbourhoods will be bigger this time. Big lots are not something I personally need under normal circumstances, I even find 30x20 too big at times, but with farming, it makes perfect sense. We're going to need somewhere to put all those crops and sheds.
