ussnorway: in the case wizardry 8 the GoG installer has a bug that stops the starting save game and the premade characters from being installed... gog knows about it (for over a year now) but this issue doesn't stop you from making a fresh party or importing the files from your game disc copy.

the game itself needs a G-card to play and the most common wx issue is that the signed Microsoft drivers for old g-cards are years out of date so if you have auto-updates (the default setting for wx) on an old vista or w7 made system then the odds are your drivers are too old to run this or any other game but there is nothing to stop you updating your drivers to unsigned w7 g-drivers and then the game runs on wx just fine.
