I am playing with a simple track method that uses a chart instead of paper IPC or recording on pen and paper. This is a very simple non finalized chart, so forgive the unpolished look.
Basically, you mark the IPC production level with the country’s disc, and you mark how many IPC’s the country actually has with an infantry piece or antother handy marker. When you recieve or spen IPC’s simply move the infantry piece to mark it. It is also usefull to track how much you are spending when purchasing units. This is particularly usefull to new players or the mathematically challenged. The following pic shows Russia’s first purchase is progress. Note the infantry sitting on top of the marker at space 24, showing how much Ipc the country is startin with. Then I add 1 infantry back 3 spaces to denote how much Ipc I have left and then a chip 3 more back to indicate another inf, all the way down to the tank. At the end of the phase you would move the marker infantry to 1, showing that Russia has 1 IPC left.
What do you think?
