FYI, Gorath was awesome. Pity Feist butchered him, he's an even more amazing character in the game. Feist just had to derail him
Betrayal at Krondor got me into Feist. (When I was seven.) Feist got me into fantasy. So it's been very bitter for me to realise what a sham he is.
See, it's like this: the best/most interesting elements of his books (to me) can almost invariably be traced back to the work of OTHER people.
The Midkemia setting was conceived together with Feist's college buddies, the Friday Nighters, for their DnD-ish campaign, set about 500 years after the events of the first Riftwar. Feist effectively wrote out the lore and ancient history they used for the game. I'm tempted to assume he based Arutha and Jimmy and the like on the game characters, but I have no idea, so let's give him credit where it's due: Arutha and Jimmy and Amos and many others in the original trilogy are awesome.
Then there's his co-written books. When a book is co-written, it is generally close to impossible to have equal shares of work or even real cooperation. At best, the writers come up with a plot together, and then one of them does the bulk of writing it out.
Did you like Honoured Enemy? I loved it. Especially the arc with Tinuva and Morvai. But then I emailed Feist about a lore error (Tinuva says "Bury me beside my brother", when we all know the edhel consider burial to be an insult to the spirit that inhabited the body). He said it was him "not catching a gaff by Bill" (as in, the co-writer, William Forstchen). So there you have it. A major climactic scene in the book, and it was written by the co-writer, and Feist didn't even notice a major lore error in it.
The same goes for the Empire Trilogy, which has unusually deep and rich characterisation. Unusually, because the characters change through time. Face it, Feist's characterisation arcs usually boil down to a Coming-of-Age story, he doesn't usually do deeper stuff.
And then of course there's the excellent game Betrayal at Krondor, which, I may note, was written entirely by Neal Hallford. Feist didn't write the story or the OC's or any of the in-game text - he was busy writing The King's Buccaneer at the time. Of course, didn't stop him from (badly) adapting the story into a novel and earning money off it. (I still can't forgive him for the way he butchered Owyn's character by making him some sort of unsympathetic comedic relief.)
Note that the Riftwar Trilogy, Honoured Enemy and the Empire Trilogy are the ones most unequivocally considered to be his best books, and the game Betrayal at Krondor is praised for its writing and likewise widely considered to be one of the best RPGs EVER.
...And then he has the gall to be an utter hypocrite and forbid fanfiction. Rrrright. Allegedly because it's a financial risk. Which is odd. The list of authors who forbid fanfiction on Wikipedia and FF.net is, what, a dozen? You'd think that if it presented an actual financial risk the thousands and thousands of writers who don't forbid it would have noticed something by now. Never mind how useful fanfiction is for keeping the fandom going, especially with books, where years can go by in-between updates. It can't be a coincidence that nearly all of the offical Feist forums have either closed down or don't talk about Feist at all anymore.
Now that Feist is on his own, he seems recycling old characters and archetypes, using a lazy and sloppy prose style (infodumps within a page of introducing a character? Really?), and generally being lazy. (Remember how freakishly short A Kingdom Besieged was?)
Midkemia is a great setting, one which can obviously be used to great advantage with love and motivation (of which Feist seems to have neither lately), but I wouldn't recommend his more recent books, and from what contact I've had with him, he seems snobbish and arrogant. That's the sad truth.
