Enjoyed the amusing idea of crew of the Enterprise nervously watching their Captain anxiously scribble down notes from the Starfleet manual as they face the prospect of a Klingon invasion. But pretty easy to get the hang off once you get into the swing of things, combat and diplomacy not really being the name of the game, rather it being an exercise in logical resource management and allocation of the kind that I've seen be a staple of games from this period. Spock would be proud.
