The closest I've seen was some data from Dragon that showed that covers featuring Elves or Dragons tended to be stronger sellers than any other class of cover art.
In a related note, it would be interesting to hear from companies like Reaper if their sales follow a similar pattern. I suspect they do: a conversation with a store owner hinted as much.
I definitely agree that there were dismally few minis of certain races, and if I were still collecting, I likely would have bought some of them. That said, I'm not collecting anymore, for reasons discussed above, and more Shardmind or Minotaur or Dragonborn minis isn't enough to encourage me to start collecting again.Y'all, I agree that there were hordes of issues with DDM, in both the 3.X and 4Ed forms. I was primarily interested in it for my RPG campaigns and occasionally in the game itself. I much preferred the business model of DDM's predecessor, Chainmail, which would let me buy lots of what I needed and skip what I didn't (beyond the bare minimum I wanted for the minis game, that is).
However, it just seemed to me as if DDM 4Ed did a lousy job of supporting the 4ED PHBs. I routinely run into players who won't play (or resist playing) PCs without "the right" mini, and "close" isn't usually good enough. So the dearth of Dragonborn minis would dissuade them from playing Dragonborn a bit...as would the lack of Warforged or Devas, etc. Ditto Elf or Dwarf minis with "non-traditional" weapons.
Was the distribution of atypical (i.e. non-Dwarf, Elf, Human, etc.) "PC race" minis in DDM OK, or would you rather the sets included more Dragonborn, Tieflings, Shardminds, Wildren, Goliaths, Changelings, Devas, Shifters and Warforged?
(Why bother using a Tiefling for 4e if yer just going to gut their fluff/crunch for some strange reason?) I really don't want a Tiefling mini if it is going to look just like another Tiefling mini in a different pose. But that's just my preference due to the game I run. If I played a 4e game, then I'd say the amount of Tiefling minis they made was fine.
