In the absence of a collective, hobbyist phenomenon such as PG2's / OG's "Campaign Challenges", actual play under PGF is, well, terra incognita. One can speculate about it ad nauseam...
Since PGF's inception and subsequent release, the "publicly" manifested main focus has been on SSI's "flagship" PG1 / AG content and its close modifications / emulations. Most likely, this tendency will persist throughout PGF's second decade. Hobbyists sticking to this tendency employ SSI's terminology without variations or exceptions. In the future, I'll be referring to this tendency as PGF-SSI. One can reasonably assume that PGF's Developer / Programmer fully intended to gift his PGF-SSI to the "hobby" and, probably, not much else...
Now, let me state the obvious:
PGF's Developer / Programmer never bothered to provide the hobby with much detail regarding the wargame's play system. At the same time, for something like 10 years, the "hobby" couldn't care less about such... unimportant matters ! This state of hobby affairs reminds me of the rather well known "don't ask, don't tell" approach to certain sensitive subjects.

The preceding notwithstanding, PGF's second decade has already witnessed a very "public" appearance and persistence of a markedly different tendency. For some time now, two or three hobbyists are known to have been treating the wargame as a computerized Content Design & Play Platform (CD&PP) of the Abandoned and Cryptic (A&C) kind.

As far as I'm concerned, PGF's "public" future largely hinges on treating the wargame as a computerized CD&PP. In fact, this Platform is both Abandoned and mostly Cryptic...
A Counter-Intuitive Silver Lining
Admittedly, PGF's programming is somewhat "rough". In fact, it exhibits quite a few generally undesirable features / behaviors.
BUT
PGF's Developer / Programmer did NOT stay around long enough to progressively render the wargame's play system increasingly... "canned", likely to be egged on by the hobby's "traditional" tendency. Thanks to his relatively early "departure from the scene", hobbyists pursuing their interests within the context of the second tendency are able to do all kinds of "offbeat things" that, in all probability, PGF's Developer / Programmer wouldn't have been interested in facilitating.

SO
Early abandonment of a piece of wargaming software isn't necessarily without some unintended... merit (e.g., PGF-CDP's "discovered" capabilities) !
