During 'Invitegate' when it was almost impossible to play alt with friends, I set my phaser to Master and went out to seek new life and new civilisation.
I have to say it was very enjoyable. I played a lot of really great games with fun people I hadn't met before and added a few to my friends list.
In fact there was only one game where the chat wasn't pleasant, the weird guy responsible quit when he went one down, to the disgust of his partner and us. It was fully expected though, the host had teed off before I could warn him about the hat guy.
I would recommend it, there are some great players out there just looking for fun competition.
