Getting at least 1 land plot, if not 2 would be a worthwhile investment. Just being able to craft the items, to be able to sell them later if you desire with a higher level building on the land and making profit while someone is able to make their own items based on your land and building, would be great.
A huge expansion this will be and it shows both how active the Splinterlands team is and how much they care about bringing the community an evolving but solid game to enjoy and make some extra money on through hard work and being a part of the game.
