Long time Privateer fan Silverforce has put together a top-down RPG/RTS space shooter, available on multiple platforms. Star Nomad features a selection of modular ships, random missions, commodity trading/smuggling and a dynamic main story line. The game is available for Android devices from the Google Play store. Windows and Mac users can get it through IndieGameStand.
Showcase here is a Centurion Heavy Fighter (quite cheap and versatile!), agile enough to dodge a lot of incoming fire, and packs twin turrets and launchers (all modules fully up-gradable) to dish out the pain. Sadly, it has next to no cargo space for trading, but there's trade ships for those who love that side of gameplay!
