User note after discussion with Devon Oratz:
Cinema6 is what Devon named his cinematic D6-based series, and Phantasm (2010) was the first in the series. Unfortunately, he never Googled it to find it was already in use with half a dozen titles. This is why my PDF and physical copy refer to Cinema6.
When it was brought to his attention recently that Cinema6 was already in use, he selected "DicePunk" as his system name and they've updated the PDFs to reflect this (apparently, after I had downloaded same). Phantasm (2010) is soon to be reprinted and the new physical copies will refer to DicePunk.
