Zemjw - whilst GZG does hold a range of scales (some 25/28mm and the awesome 1/300 dirt side range - ooh and the excellent full thrust ships) the majority of their awesome miniatures are in 15mm (sorry, great for me not so helpful for you

). 28mm is usually well provided for so there must be some scale suitable equivalents out there - maybe search for lunar threads here to see if anyone playing it have some suggestions
Cat - I don’t think it was Star Grunt (I hope I would have recognised it as I’ve spent many hours playing it - but no guarantees

) and I seem to remember seeing a QRS note discussing different coloured dice………
Going to search my phone and hope I have some more informative pictures - had a look but unfortunately no.
