I have played it a couple of few hours in sporadic fits. The demo scenarios are not very good at showing off the product. The faults in the product stop me from buying it. So, the demo has not achieved it's purpose in my case.
It would need fixing and a rerelease in my opinion. Hopefully, with some better scenarios also. Why they don't release a small, medium and large scenarios in the demo is beyond me. Or a small infantry, and a medium combined arms, and a big sha-bang with the Eight Air Force etc.
The game release seems to actually 'model' the actual invasion. The invasion took its sweet time and blundered into very bad terrain. Has the demo done the same thing? My history teacher would be waving a stick at them. "Those that don't study history are doomed to...".
I have actually played full PCO games more than CMBN and I haven't played much PCO! Maybe the wargame companies just need to lick thier wounds.
