Nah, nothing that dramatic (the destruction of suns and planets, I mean)--at least, I don't think so--but there is combat. Quoting PCGamer December 2001, page 100: "75 planets, 145 moons, and over 100 space regions"..."over 60 different spacecraft and planetary vehicles available to be flown or driven"..."It's kind of like someone tossed you the keys to a starship and simply told you to 'have at it, sparky.'"
The last quote was really their only complaint about the game--its lack of structure. I never played it myself, but I trust PCGamer's opinion, and they gave it a 77 out of 100 (which ain't bad, especially for Derek Smart); yeah, it sounds alot like a free-form Star Trek game. You can control navigation, weaponry, engineering (aka power management) onboard your ship, beam or shuttle down to planets to explore, trade, etc...again, sounds like Star Trek meets Privateer. Personally, if I could find it in a bargain bin or cheap on eBay, I wouldn't pass it up.
