I am already using Facebook as a means of saving my user info, and many of my Facebook friends are getting the game. I think playing matches with friends would be great. I have two ideas for this:
- turn-by-turn game where you make a move, and are notified when your friend takes their turn. Same for when they make theirs.
- searching for friends on your Facebook friends list who have the game and are logged in, and initiate a live match.
Not sure how possible this is but my friends and I think it would be fun.
