Pocket Gamer: Spice Invaders is about a civilisation in complete thrall to a precious resource, and it's prepared to wage war to obtain more of it. Sounds suspiciously like a parable, doesn’t it?
But breathe easy. The civilisation in question isn’t human - it’s an invading armada of Space Pirates. Human beings are the innocent party for once, because it’s their planet that’s being plundered.
