I still think that there are absolutely
NO patterns in FIRST games. I have a theory that when the GDC (or maybe Dean alone) has their first "meeting" they come up with a new(or old) concept in engineering, technology, etc... And then they build a game around that concept in order to teach/introduce students, and even mentors, about this idea.
This has absolutely
nothing to do with any theories about what
means, but that is my idea on the thinking of the GDC...
Maybe the 5 has something to do with the number of periods in each match. Or maybe the time interval between colors changing for the CMUCam...
