Huh....interesting. All the bits are as in the photo? I have never played anything like this; would it be a good way to wet my toes into wargamming?
Yeah, you cut out the bits on the right, and the rules are on the back.
I don't know how it'll be as a toe wetter, but if you geekmail me your address, I'll send it along and you can try it out.
The rules don't seem that complicated, but they're packed pretty densely onto the back of the postcard. Not surprising based on the small area available, just a warning.
