The option to literally carve — or pave, I guess — your own path is one I didn’t realize I wanted so much. Fortunately, New Horizons provides it. It’s not clear from trailers whether you’ll need a specific shovel, though it looks like you will. But it is clear you can make walkways, little clearings, or whatever else you take a notion to making that involves not having grass.
City Folk tried this with that bizarre “walk on the grass and it disappears” mechanic, but I greatly prefer New Horizons’ method of giving you more control (and less dead-looking ground). Surely, we’ll still be able to plunk down paving squares of our own design as well, but the option to take the natural route is much appreciated.
