There's a couple of good deals over at Steam this weekend. The price of TaleWorlds' sandbox RPG Mount & Blade: Warband has been reduced to $10 (66% off the original price of $30) , while the prequel Mount & Blade is only $7.50 (although I've seen it being sold at $5 on Direct2Drive before).

Doctor Entertainment's Puzzle Dimension has been getting a couple of good reviews lately, and to celebrate the release of a new Mac port the developers have reduced the price of the game to $7 for a limited time only (33% off the original price of $10). There's a PC demo up on Steam that you can try out before considering a purchase. Unlike the other two, this promotion ends on September 1st.
