What type of collectibility are we looking at? Something like ole Mage Knight with high levels of variety or something simple like WoTC?
In some ways, as a miniature collector first, the size baffles me. 25mm, while not 'dead', is not the standard used by most companies which are going larger, 28-32. Not a huge problem with the monsters in most cases but...
Well, I guess I'm having a 'flashback' to Dreamblade where WotC essentially spit in the face of the D&D players who might have wanted to use the miniatures with their D&D games by making the figures somewhat incompatible in scale and massively incompatible with the bases which required too much work from the typical buyer.
Not saying that this game will suffer that effect but if one of the periphial miniature buyers you're looking for is the casual gamer, I'm not seeing 25mm as the way to go these days.
