"They get a bit of a caning" Not surprised, bought the new set of the rules with cards and while very nicely presented, really nothing new and nothing changed. Of course, we were all warned that was the case, so not complaining.
While the rules in question inspired my MASSIVE collection of Old West figures - and Pony Wars, too - I have opted to rework an old set of Tom Dye Minifigs/GFI rules called Bite the Bullet. Especially because I want one core set of rules for many different things. Lot of work yet to go. But at least the miniatures are moving forward in getting painted.
I suspect a lot of the more well known Old West rules took some inspiration from Bite the Bullet - and perhaps some of the oldest may have inspired BtB.
Still debating how to at least use the cards. Might pinch some things from the rules. At least the new version of the rules is much more readable.
