I'm not sure if there's an easier way, but I just save edit a new game: start a new game, and save it as soon as I'm into the world (try to leave at least 1 skill/talent/magic point unspent). Open up the save file in notepad or something, and change the lines for food, money, skill/talent/magic points, adding a bunch to each, and edit my stat points to truly broken levels (I usually do 7 str so that wolf girls don't rape me, and then like 14 everything else, and end up using a rapier).
Keep in mind, of course, that this DOES break the games back, as far as difficulty is concerned, so only do it if you've played it through a time or two: it's like using cheat codes.
