Superb, Star Fleect Command 3 is so far by far the best Star Trek RTS game!
Graphics- this game was released right before the movie Star Trek: Nemesis (which is a good movie I might add) came out, so the graphics are a couple of years old, so their not the best, but considering the time period it came out, i think they're pretty good.
Sound- The sound in this game is incredible. i really love the sound, sound effects come straight from the movies and tv series so it's very authentic to what it 'would sound like'.
Gameplay- there is a lot of stratigizing in this game. Although you are one ship, you must take care of it and make decisions on how to keep it up and running during combat. For instance, do you want power to go to the shields or to the forward torpedo tubes. It gets very immersive.
Conclusion:
Star Trek command 3 is a very cool game and I recommend it to all types of people for all ages.
