Moonlight Falls looks good -- the pre-Seasons park lot was very empty and boring, but the festivals fill it up nicely. One amusing issue I found was with the broom riding arena. Summer places it in the upper right corner, fall in the upper left When I clicked on my broom during fall and selected a joyride, the Sim would ride around in the now-empty corner instead of the arena's new location.
Appaloosa Plains is a letdown because, due to a lack of a proper big park in that town, it instead replaces an empty 50x50 residential lot, one of the better ones in town. Compared to the rest, it does look like a half-baked job especially when there's no festival going on.
