Ah, another Disciple! Let us join forces
Seriously - while we are all waiting for Book III, I can only recommend trying this one as well. I mean, it's free, and indeed has more quality to it than quite some games other people ask money for. Currently I'm playing through the custom campaign some other guy has created...
... @Basiliskgames: If you are actually going to include an editor in Book III, I think you could do worse than take a look at this one. Its editor is easy to use and boasts a huge number of pre-made events, which makes building your own levels that much easier as much of otherwise necessary scripting has been done already!
@quasimodo: Try a Willpower-based character with Prayer and Curse skills. This has quite a bit more flexibility than the simple warrior!
