Buy the series DVD's instead..
I have never to this day seen a worse movie/series to game title than this one. A top down shooter copy of a show with deep storyline and awesome cinematics on the big screen? What were Sierra thinking publishing this piece of binary crap.
Any game based on this IP should have awesome graphics, physics, sound, game play and narrative. It should be on par, if not exceeding, with X3 and EVE combined.
This game, has none of the above. But at ~200mb before install, what could you possibly expect.
Like the title says, buy the series instead. It's an awesome sci-fi show.
