The game is set a longer time ago in a galaxy far, far away, and sees you trying to stop an evil Sith from destroying the Republic with an ancient war machine.
When we reviewed the iOS version we said "despite some control workarounds and dated visuals, Star Wars: Knights of the Old Republic remains a truly exceptional RPG and one of the best Star Wars games ever released on any platform."
If that's not reason enough to grab it on Android, the game is on sale to celebrate its launch, so you can pick it up for £3.20 / $4.99. Which is frankly ridiculous.
