I interested in usual time of play in this game. I can not find this information on KS. As the rules are still in beta, and the game can be played with very small fleets all the way up to huge fleets, it's probably hard to say how long it would take.
There are fewer models, and less terrain, so it seems a bit less fiddly than say, Dropzone Commander. My guess would be for the starter fleets, 45 minutes to an hour, and for a full tournamant sized fleet - probably 2 hours for experienced players, more like 3 if someone's new to the game.
