Back to putting the thread on its tracks
Looking again at the D2 screenshots, IMHO the problem with the graphics come from the units sprites : they look pixellated even from somewhat afar, as if the bitmaps were quite (too) small...
To get a better aspect they should be doubled in pixel size...But this involves redoing the 500+ units sprites
!
Unless the gfx are moddable (in external common format files) to allow fans to do them I don't expect Illwinter to be able to do it quickly ... but maybe I'm wrong (who am I to doubt
) ?
