This is a simple question, and it could've been very easily mentioned and I just missed it (loud trucks driving past me for half the video), can you play specifically against friends?
I heard them say they have systems for playing against random people and A.I. and such, but I didn't hear anything about a friends list, or being able to say to someone, "Hey, let's you and me play a game!" Maybe I missed it...
Did they mention anything like that?
