Great games that rock the nostalgia vote, poorly emulated for your playing pleasure!
Well, for those who think like me, I have good news, and I have bad news.
The good news is that Sierra / Vivendi hasn't turned a blind eye to the classics, as proven by this re-release of the King's Quest series in its entirety (minus the abomination that was KQ8). The games are fully emulated to work in a WinXP environment, and will even operate in a Windows Vista environment (for all you riding-the-bleeding-edge techie types).
The bad news is that Sierra / Vivendi's idea of "retooling" the classics to work in Windows XP / Vista is to tack an autorunning and autoconfiguring copy of DOSbox onto each title which, while workable, gives you a lot of audio and graphics glitches during the cutscenes (most noticable in KQ6) due to the program's apparent inability to properly throttle CPU usage. (Note that identical emulation errors occurred on both a WinXP desktop and a WinVista laptop).
Still, the glitches are negligible at worst, and shouldn't stop one's enjoyment of these seven classic games at a wonderful bargain-bin price. Some places have this title on sale for less than $10, if you look hard enough. Even at its full $20 price, however, this package is still very much worth the purchase.
