Falin, PE didn't just wake up one morning and close down GnH, they closed it down because one of thier main investers was having major financial issues and pulled out, this meant that PE no longer had the funds to carry on production with GnH and was forced to close it down. It doesn't matter how close the game was to release, without funding to finish it off and ship it there was nothing to be done.
Same goes for STO, the reason the plug got pulled is because the publisher pulled out days before the rumour that STO was dead, Its worth noting that the same publisher ditched a few other titles as well as STO that same week due to a refocus in thier titles. Once the publisher pulled out the investers followed, afterall, the publisher is an extremely important part of the process. The PR blitz literally wasa week or so from happening until the publisher pulled out. This comes from a couple of contacts at PE which are extremely reliable.
Sure, the management at PE were rubbish at the PR side of things, but alot of the problems GnH and STO suffered were invester and publisher related and not something PE should be held entirely accountable for. STO was one hell of a lot further along than alot of people realise, I saw the space and ground aspect of it myself over a year ago (ingame engine player live). Most of the concept art that was getting released was well over a year old when the public saw it.
Ultimatly, I'd say the PR side of PE was aweful, theres no refuting that, but the talent of the development team was extremely awesome.
