The Humble Bundle site is the source for a small variety of games from time to time for less than my two cents.
Today, until October 12, HB is selling Frozen Synapse, and if you pay more than the average, you get the Frozenbyte bundle, as well, which is, in my opinion, a nice set of games.
Frozen Synapse, thanks to this bundle deal, will receive a review on GL in the near future. I really hope the new deal ends up having more games involved, though. Fingers crossed.
