Plains. For some reason I find Fulings hilarious. Their sounds when they notice you crack me up and they are fun to drag into places like the Swamp so they can steam-roll raid the entire thing - good entertainment. I also like the giant stone stuff in the Plains and in general I like the autumn look of it. I also like seeing the Growths go to war with basically everything, including the Plains creatures.

Meadows are ok too but I am sick of seeing and hearing Grey-kin between the two staring biomes, they irritate me. I'd probably put the Mountains second to the Plains.
