Hi,
1) Sprites work by dynamically creating a mesh each render world. But the mesh is drawn in 'chunks', with renderstate changes in between. Blitz checks for redundant changes, though, so the overhead isn't too bad. Still, this could be dramamtically improved using vertex alpha/color.
4) I would recommend reducing the size of your units! You may have future problems with zbuffering and collisions.
