The Errata provides the fix - it is not the blazing hills that is a major issue in the CG - it is the fact that originally, the fires ALWAYS got bigger and never went out until they ran out of things to burn that made the CG unplayable if something rather common like a large caliber NOBA or a MOL-P hit on the first CG date, started a forest fire. That errata was necessary, and it at least contains the fires - but they can and often do, re-spark from another MOL-P hit or another NOBA or aircraft bomb hit - it is the fact that even then , those fires go out in between scenarios that makes the blazes something both sides must consider, (a realistic assumption of the historical commander's issues), but not now something that degenerated into a game of Advancing FIRE phase DR's that went on forever, (and worse, if/when a Gust or breeze appeared). (maybe realism (in that case) run amok, but playability has to come into focus in a design for effect game like ASL).
I believe the CG is playable and a good run with the Errata, and unplayable and not a consideration on my part as something to play, without the Errata. As with most things, YMMV.
