Interesting I will give them a go and see how they fair but with fast play rules I always find there is something missing. I started to write my own rules for Napoleonic 15mm trying to incorporating the best of several sets of rules. I achieved this but I had a stack of papers ceiling high. Play tested them smoothing out the wrinkles and attempted to condense the paperwork. Then one night in the pub one of my mates joked 'put it all into a computer and let it handled the complexities' that was 15 years ago. At first I learnt to program in visual basic 5 then micro-soft upgrade the program language, so I converted my program to the new update. I got so close to completion when Micro-soft upgraded again to Visual Studio 2017 so once again I had to convert the program language. It's nearly five years on and I am sure micro-soft will update again and I am so very close that hopefully I should have a working set by the end of the year (actually I got it working I'm just debugging it). Its amazing how having a pint with a mate puts you on a life long mission to complete a project.
The Software is free its when you publish you pay for it. The problem is when they update the software they add new stuff and change other stuff and before you know it, it no longer works and you have to go back and alter what you have done to get it working. Sometimes they throw the old software away and no longer support the product or change it to a brand new type like they did for Visual studio. Bill
