The Gorn especially was really hard to look at. And while I appreciated the different looks for each race, moving the buttons around made it often a challenge to transition from race to race. I also found that neither base view was entirely satisfying. The overhead view could not be rotated, zoomed based on the distance to your active target, and targeting other ships and getting information about range, etc. was very hard to do. On the other hand, the chase view made it nearly impossible to sere the shield status of enemies, and even differentiate between friend and foe far too often.
Music differs for each race and was excellent throughout.
The martial strains of the Klingons and the more uplifting Federation themes are recognizably Star Trek, but my favorite was that of the Lyrans. Sound effects are also well done, the sounds really help play the game. The sound of the transporter can alert you to events like boarding parties invading your ship which might otherwise be missed in the heat of battle for example. One serious problem facing Starfleet Command were a series of crashes and hang-ups. In the final analysis Starfleet Command is a game that will appeal to the serious strategy gamer.
