As we announced on Monday, this week's Xbox Live Arcade titles are the puzzler RooGoo and Sierra's space shooter Aces of the Galaxy. Now while I've been following RooGoo for quite some time, Aces took me completely by surprise, mainly because it hasn't really been mentioned since it was announced back in October
. It's almost as if Sierra forgot to market the game, but now they're making up for lost time with this trailer and a load of screenshots to help you decide whether Aces of the Galaxy is right for you. Go go Sierra marketing squad!
