Check out the Riftrunner FAQ and interviews; Larian has already addressed most of your points. I don't know how many voices there will be, besides male/female... you can play as a child, though, so that implies an additional couple voices. If the character does not say much there may be lots of choices; if it does, there would be less. Hopefully Riftrunner's publisher will be more supportive when it comes to developing patches, not to mention promotion.

This isn't horse shoes or hand grenades, but at least you were close with the forum. <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />
