I have created an Axis & Allies variant inspired by the simultaneity mechanics of Diplomacy. It is an online game with all the game state stored in the server, so the players use a simple web browser to play. The manner of play I envision is each player or possibly each team uses a physical board to track the game, and the online game provides the interface to create orders for the units, shows the outcome of conflicts, and provides an interface to execute and settle multi-unit battles. Having a physical board and pieces isn’t necessary, as the game is tracked on the server, but I expect it is more fun to play along with physical units. The current user interface is crude, but I think it’s sophisticated enough to be effective. I’m looking for someone to help me play-test the game and provide feedback. I will likely create a new user interface to overlay the existing system, but I need to actually play it a bit with a real opponent to know what direction to go with that. If you are interested, you can read the docs here:

if you are further interested in seeing the interface and play-testing with me, send an email to concurrent-aa-play-request@coyotebones.org. Please send from a real email address, as I will register the address for your login to use the system. Include in the message a nickname you would like to have on the system so that your email address is not exposed to other players.
