One off topic question about the 3D characters. If they are to consist of one part only, does that mean that the characters will not show any motion during the game? If the character consists but of one lump I reckon it would be impossible to see them move their legs / wings and they would instead be shifted through the landscape like they had frozen in motion, wouldn't they?
Creating animations of character movements is probably a whole big story we haven't ever mentioned so far.
