So I was thinking about making a very small, very quick-play wargame, and that's how I made Wargaming-Z ("Z" standing for "Zack", don't you know). It won't win any awards for ultra-realistic tactical whatever whatever, but it fits on a single page, and I think I can do some fun fantasy wargaming with it without having to memorize any more than a couple of rules.
You can check out the very short, very free Wargaming-Z version 0.3 here. Please, if you do play it, I'd love to get some feedback emailed my way! I'll be releasing some sample units or templates in just a bit, but I think you can see how it'd go.
