If you haven’t already, I highly recommend that you head on to Steam and purchase DEFCON. This is a brilliant thermonuclear war strategy game, from the folks who brought us the insanely great Darwinia.
The retro style and simple premise do not imply the underlying complexities of planning to kill millions of people in your opponents’ countries. The game is instantly easy to get into, but working up effective and unique strategies can be an entirely rewarding and challenging experience. It’s like Risk in a way, except at the end the death toll is usually in the hundred million plus range. Check it out, and look me up if you’re online and want a match. I’ll give you two guesses what my Steam name is.
