I always saw Molyneux as more of the "traditional" hype man (or conman) in the video game space. Promise the world, but actually deliver some lesser product.

I genuinely think Roberts is just unhinged in this way (or maybe he was before he got this ridiculous endless funding stream). Grand visions that he won't let the minor annoyances of software engineering get in the way of. Tetsuya Takahashi's another one like that.
