Llamaland: My Favorite Mechanism

About Llamaland, from BoardGameGeek:

The plateaus are wild, stunningly beautiful, and...full of llamas?! Being a farmer in Llamaland isn't exactly easy with all the hills and mountains around, but even so, growing potatoes, corn, and cocoa on the slopes of the mountains is what you love. Luckily the llamas are a big help, too! By fitting your fields in giddy heights, you gain the necessary crops in order to obtain the desired llama cards. These cards not only provide victory points, but also allow you to place a llama on your farm. After about 45 minutes, you will have an impressive crop-growing area in front of you, including your sweet and cuddly llamas.
