It's ok to have a game be a Vassal module. It's not ok for the game to be so undeveloped.

So, four pages of rules (the PDF has five pages, but the fifth is completely blank). There's not much text on those four either, leaving lots of questions. Let's start with a basic one: what happens in a turn? No idea. There's something about movement, and something about combat, but no turn sequence.

Stacking is perhaps the most complete section, but... "Stacking in any Art of War D10 game is not allowed, unless stacked under a commander." OK, unless it's with a commander, you can't stack. "Otherwise each square can hold 4 tokens." Otherwise?!? You can't stack unless you're with a commander... and if you're not you can stack four things?!? How many can you stack with one? "A commanders stack only counts as one out of the 4 spaces available in the square." So, you can have as many as you like, but only four commanders? etc etc etc.

Utterly unfit for purpose and for purchase.
