It is strange, never seen anyone with these figures, those rebellion rules look very professionally produced but can't come across any reviews?
An early version of the rules, which was available free on the website iirc, had many similarities with Games Workshop's Lord of the Rings skirmish rules, which for me was a plus. It wasn't restricted to just d6s, though, and there were some differences that I can't recall.
Unfortunately I don't know if the current (very nice-looking) rules share that lineage, or are an entirely new set of rules. I couldn't find any reviews either, and I think they're a bit pricey for me to consider buying without knowing more.
