Ryan: Yeah, the game is different if you play it alone or with friends. Alone, when I was done building my house, I was ready to call it a day. With friends it changes entirely. You visit their creations, they visit yours, you inspire each others, you build stuff together, you hide secrets and search others' secrets...
By the end of the month we had houses, 5 castles, pirate ship, a corner of the map full of video games sprites and references, a downtown area, a graveyard, a giant tree and an entire menagerie of giant animals and dinosaurs, more stuff build underground and roads, bridges and tunnels linking all our stuff. Depending how creative you and your friends are, it can be really addictive.
