The latest Humble Mobile Bundle offers 12 Android strategy games for just $5
Unlike many previous bundles, the Best of Strategy foregoes the classic BTA (beat the average) middle tier, and replaces it with a fixed-price one. Otherwise, the bundle is pretty conventional, but still full of pretty good games.
$1 or more will get you Epic War TD 2, MechCom 1 and 2, Age of Civilizations, and a $5 in-app purchase for Battle for the Galaxy. The middle tier of $3 gives you access to Anomaly Defenders and Anomaly 2, Kingdom Rush Frontiers and Origins, and Hero Generations. If you pay $5 or more you'll also get Guild of Dungeoneering and Worms 4
Overall, this is a pretty solid bundle, though one could argue Humble is stretching the meaning of "strategy" by including tower defense games. It's also a great value, as the games are otherwise worth $47. As usual, buyers can choose where the proceeds go, including to developers, charity, or Humble itself.
