Drox Operative - Preview @ IndieGames.com

IndieGames has a preview for this game. A quote about the races:

Impressively the game offers a huge selection of playable races that cover everything from typical fantasy fair to Babylon 5 references yet lack the Drox. These have apparently been extinct for thousands of years and all that remains is the secretive Drox Operative guild. Said former servants of the Drox have discovered that -having barely avoided extinction while trying to serve the galaxy- survival and power are of paramount importance, and now only work for the highest bidder as opposed to the collective happiness of the galaxy. Added to that and rather helpfully they are probably the best and most expensive trouble-shooters any space-faring race could hire.
