My fondest memories of the original Star Wars films were the starfighter dogfights. The first time you see the assault run on the Death Star, or the ill-fated attack on the second before it was finished, it's really cool to watch a bunch of fighter craft flying around, blowing the heck out of each other. Every once in a while, you can get the same sense of scale and calamity in a game - usually of the real-time strategy variety.
The Humble Bundle for Android isn't just a great way to get cheap indie games and help charity - it's also shaping up to be a pretty great platform for launching Android ports. Take Eufloria: it's been available on Steam for PC since 2009, but once it came to the Humble Bundle, it was made available for Mac and Linux too. Now the game has been released to the Google Play Store.
