grviper: If they have DOS Wiz7 there, I'll buy it on a sale. With free cards money.
It looks like Wizardry 7 includes both versions; the store page lists OS X and Linux versions while also saying "Wizardry 7 Gold is currently only available in English and on the Windows platform".
spindown: Interesting. This might suggest that Night Dive was somehow behind the GOG re-release of Wizardry too.
The more likely explanation is that Gamepot hoped it would build interest in Wizardry Online--note how a Wizardry Online promo is shown in the GOG installers whereas normally you only see ads for other GOG releases.
