I'm currently in a Hot Seat Game right now with one of my friends. It's a great way to play as theres no waiting for the upload of turns, but you must be prepared to have your friends entertained while you do your turns. Of course i have played a game where we both just watched each other so we knew exactly what each other was doing and it was one large counter move after another, it was a fun game! But i prefer the feeling of suprise when you send your fleet through an enemy wormhole
