Damn...In his defense, ICE is between a rock and a hard place here. Him and SE worked/played closely on the roleplaying and world-building that resulted in the greatness that is the Malazan universe so he has a perfect right to pursue his writing ambition within that universe. Would he have been published as soon as he was had SE not broken the trail? Maybe not, but that's not ICE's fault - he'd be a fool not to take the opportunity and get started on the path that he obviously loves. Anybody who can muster the discipline to sit down and write for months on end, knowing that they'd be subject to the slings and arrows of every keyboard warrior out there must have a great deal of discipline and love for the material. So give him a break - he's not SE and has to develop his own style. He's been thrown in at the deep end with an established fanbase that is naturally going to rankle at every little departure from SE's approach to the material.
The cost of his first books was a function of the nature of the publisher that was willing to take a risk on him at the time, not his fault. He has a 5 book contract with Transworld now so that's not an issue anymore.
I think Nok was actually really good in a completely different way to SE's work. Admittedly, I was a bit disappointed that more was not revealed about K&D's two-year sojourn but I think it was a solid effort.
With Return, as others have said, I think he was trying to be too much like SE and it didn't come off. It wasn't terrible, but I think it could be characterized as 'muddled'. And a personal pet peeve= Kyle? WTF? Kael, Kale, Kyal - any variation would have been better, but such an obvious modern name just kicks me out of my suspended disbelief and I cannot fathom why he chose to do something like that. Anyway, loads of problems with Return, no question.
I think we'll really be able to take his measure with Stonewielder, since he'll be dealing with a continent we've never visited in depth before, presumably with characters all his own and hopefully play to his own strengths rather than trying to ape SE's style.
If ICE is listening, the one thing that I would try to communicate to him would be to avoid using characters that SE has already introduced as much as is possible because it's guaranteed that the fans will prefer SE's version. For example, Iron Bars in Return just felt wrong, not bad, just wrong. If it had been Black the Elder or another Avowed we had not previously seen on camera, it would have been absolutely fine.
This is why I worry about the Darujhistan novel. So many loved/hated characters in place that have been established by SE and he's never going to do them justice in the eyes of the hardcore fans. I admire the guts but damn...well I hope he pulls it off
