Thanks for the replies guys.

I'll agree that expense is potentially an issue, but I really have no idea what they'd cost. Also, although I would like to legally sell these, but I am not quite sure that I can, and they may not be a viable product. If I can't sell, I'd certainly provide them for free online, and then the only cost would be for printing and paper.

That said, buying miniatures is expensive, problematic, time consuming, and places limits on what you can use, while you could easily just used coloured counters instead -- but people do it.

One way or another, I'm glad people like the designs/the idea, even if they wouldn't go so far as to buy them. :)
