Squidmaster: Can anyone remind me how much mouse control is required in all three of the available games?
Wizardry 6 and 7 can be completely controlled from the keyboard when in keyboard mode (see below). Wizardry Gold and Wizardry 8 are built around mouse input so rely on it for the inventory/journal/etc.; Wizardry 8 has expansive hotkeys for all common combat actions (and also quick saving/loading) but still requires mouse input for the inventory and the like.
The English DOS version of Wizardry 7 is a separate download in the bonus content, not part of the main installer.
For Wizardry 6/7 keyboard mode:
1. At the main menu choose (Game) Configuration.
2. Change the Input device to Keyboard and save your changes (for Wizardry 6 this is with Exit).
3. The game now remembers this mode and is completely keyboard controlled.
EDIT: simplified steps; I somehow overlooked the setting for forcing this.
