Wow. It’s not often a game impresses me with graphics or technology anymore, but Drone Swarm [official site] is immediately a thrill just to look at. It’s a space-set singleplayer RTS in which you control a swarm of 32,000 drones. You click to direct them and they swirl as an undulating mass, each little ship individually simulated. You must watch the 11 minutes of video below, which shows exactly what you can do with such a swarm.
