Can't really argue with that either, I just can go with the things I know about the man and while it is all very little I am still hopeful and prolly blue-eyed in many facts.
Still, what I do know about the man as of now is that he has always had great ideas and great visisons, both of which he always had been laughed at, ever since I first heard of him. While he sure didn't bring up anything that revolutionized the industry but he took nonetheless rather daring and (too) big steps and demanded things that were just not done up to that point in such a scale he invisioned.
Don't get me wrong now, tho. I certainly don't defend that man for his brain-farts, he always ended up loosing the big overal picture and lost himself in ideas for which the industry wasn't really ready yet or the games simply not capable of, but in the end he does make for a nice scientist who experiments and pushes the boundaries (if only in so few aspects).
And yes, I call him delusional, as one interview he had with our local magazine here once showed clearly he thinks he's better than so many while he has yet to come up with something as successful as Portal for instance. (I can't recall any passages or look it up yet, but let's just say: he really thinks like he would be of higher ranks)
Still, a creative mind in this business if only people don't let him keep command over a game but simply as a maybe higher ranking advisor of some sorts.
Then again, we all have seen Dschafar (or however he's being written) from Alladin, didn't we?
