They need a better midi synthesizer; and hiring a musician might help. IMO - very generic, and in some part sounds out of tune. (and I'm not try to knock the score, I have a few friends who have done musical scores and arrangements.)
But it's a browser game, so I'm not surprised by the 'quality;.
I agree that the quality of the song isn't great. However, the arrangement sounds more like "Trek" than most of the music in STO. I really think STO needs some more slow songs. Everything is so fast and frenetic.
I tried their BSG Online game yesterday. I loved that they used Bear McGreary's soundtrack.
But I felt that they did not necessarily play the right titles for the scenes. And the game was meh. I hope someone has played it and can tell me the storyline, though, because I am a sucker for stories.
