Build a ship, get a crew, explore the galaxy, and find something to blow up
A particularly great space sim game made its way to Android today called Star Command. Players guide a vaguely Star Trekky crew through a wild and weird universe of adventure, upgrade their ship, and fend off attacks against boarding parties and heavily-armed alien spacecraft.
Star Command actually made its debut on Android in the Android Humble Bundle last month, but it's great to see a wider release. Don't let the retro graphics fool you - the gameplay involves a little bit of twitch with ship combat mini-games, a lot of strategy when figuring out crew positioning and skill upgrades, plus the awesome writing will have you thoroughly entertained for some time.
The download link is above, so get crackin' for $2.99. If the trailer below doesn't sell you, I don't know what will.
