I'm in the middle of a weekend at PAX Aus running edible wargames and having a blast. If you yourself are reading this after having met me today, Hi! I had a load of fun today and hope you did too.
I had a lot of people asking where they can get the rules for Tiny Teddies Go To War, Entree Invaders, and Rocky Road Warriors so I've directed them/you here so you have somewhere to look for them when I put them up after the weekend is over.
In the meantime, last year's rules can be found here, but I think that this year's ruleset is much improved since then.
Regardless, there's nothing stopping you from whipping up a set of silly rules and giving it a try yourself. That's what many other people before me have done and I hope you do it too.
I'd love to play your version.
