If you're planning your next XBLA purchases for the next few months then be sure to not count out Sierra's upcoming library of games, because they actually look promising.

The crew over at IGN got some hands on time with all six, count 'em six, of developer Sierra's new games that are set to release on the Xbox Live Arcade this Winter. So, enough of the fluff let's get to the goods. Sierra's bountiful and very diverse Winter XBLA lineup includes a 3D space shooter called Aces of the Galaxy, a mystical hack, hack, slash slasher called Arkadian Warriors, the TV based Battlestar Galactica, a puzzling bunny game called Boogie Bunnies, a casual gamer's RTS Commanders: Attack of the Genos, and finally Switchball. See, we told you it was a diverse group of games. You can check out IGN's hands-on take of each Arcade title as well as screenshots and video from each game after the jump. And with such an interesting lineup of adventure, sci-fi, shooter and action based games we can't help but be most excited to play Boogie Bunnies. Dancing bunnies ... what more can we say?
