Year: 2005 Platform: Microsoft Windows, Linux, Mac OS X, Xbox Live Arcade Considering the extent to which Darwinia defies conventions and is almost a genre of its own, it's probably no surprise that the game just wasn't destined for the mainstream. Trippy, exciting, and oddly affecting, Darwinia is one of the most unique strategy titles ever created. Darwinia is a god game. It's a real-time strategy. It's an action game, puzzler and hacking game. You'd be very hard pressed to find another title that blends so many different genres in such a cohesive manner. Unlike many on this list, Darwinia is easily available through digital downloads, with no compatibility problems, so you have absolutely no excuse to try out this gem of a game today. https://www.youtube.com/watch?v=o0MECqgaTmc
