Played on windows vista64.
I have played previous Star Trek games, like Voyager elite force & bridge commander etc... and although this game was a bit shorter than i would had liked, i really enjoyed it overall.
Basically this is all about flying Federation starships(SP mode) to complete missions, with the main goal being to chase a villian through the Federation timeline of famous ship Captains. You get to play as J.Archer, J.T.Kirk & J.L.Picard. All voice acted by them, or very good impersinations. The voices of C.Janeway & B.Sisko are also here, but not playable sadly(although you can purchase the ships they use at that Federation era for your fleet).
Off the cuff, Being linked with the company "Bethesda", Elder scrolls players will recognise some familiar voices of that series. For example the Klingons are voiced by the same person who voices the Orcs in the Elder scrolls games.
The ships and enviroments all look amazingly realistic, which imerses you, even if your not a die hard fan. On the downside, the games planets, are comicaly small compared to the size of the ships, but it doesnt make the game any worse, as its mainly ship to ship battles. Some of the missions are amazingly difficult too(filled my swear jar).
In each scenario, you gain command points for acomplishing objectives and for the number of enemies you kill. You can then use these points inbetween missions to purchase varied classes of ships as you like(of that Federation era) for your fleet(max of 4 incl. your flagship Enterprise). Obviously the flagship(Enterpise) cannot be changed.
The controls are pretty simple too, i basically used the WASD keys for ship movement, and i completed the game this way. I would highly reccomend replaying the first few missions, so you get used to the commands of using other ships, and controling your own etc. Now....Engage!
