There is this Polish RPG game called Neuroshima. The game setting is a post-apocalypse (Earth) torn apart by a war between humans and machines. The remains of humanity took shelter in the ruins of cities and organized in small communities, gangs and armies. The problem with the game is it is only in Polish. They haven't done any translations into other languages.
Fast forward a bit. Z-Man Games came out with a board game called Neuroshima Hex. If you haven't played the game, you should. It is a fantastic board game.
Fast forward to today. Big Daddy Creations has come out with an iphone, ipad app for Neuroshima Hex. The app is awesome. Here is some info on it.
