I have had the strange urge to write up a game design spec for MySins, a mash-up of bizarre concepts. Ships floating around with green diamonds over their bridges, looking for other ships to build relationships with and bridging the unholy gaps of trust between worlds.
Something about trying to keep your capital ship crews 'happy' by meeting all of their needs strikes me as endlessly amusing. "The TDN Acheron is experiencing antimatter deprivation!"
Actually, I believe Sins is a direct starcraft clone. Both games feature exploitation of the underclass. While starcraft forces you to put them to work mining and building in dangerous, non-unionized conditions, sins masks its theft by making you *tax* the underclass instead. Ironclad cleverly disguised its derivation of starcraft by giving the game a modern, 3d graphical engine, thus ensuring that we'd never, ever draw comparisons to a ten year old 2d RTS, and discover the recurring theme of economic oppression.
