It's currently $27 on Amazon!

It plays online about the same as other games. There's only one friend code to a system, but each friends needs to add the other's friend code for online play. All that's left is to open up the gate at the train station and have the other enter their town from the same place. Once you've registered each other as best friend's in-game, you can freely send messages to eachother in-game regardless of whether or not your gate is open. It's convenient once you get the ball rolling.

I regret placing my campsite by my town hall. I can't demolish it and put it elsewhere, so I can't put a fountain down nearby without it looking weird. Oh well. I'll have to demolish the fountain tomorrow and look for another place to put it.
