He seems to have lost sight of what might be the most important skill one could have in any kind of venture, creative or otherwise: The ability to plan for failure and adapt. Ken's ego is blinding him to the very real, extremely likely prospect that his project will fail. Whether this is through the clear lack of quality demonstrated by most of his other projects, or through the untold amounts of money he's piling into this is yet to be seen. He's counting his chickens before they hatch without ever thinking to check to see if any of them are rotten first.
Unfortunately, many people view comics as little more than a springboard for launching an IP empire rather than a legitimate artistic medium unto itself.
Ken's passions lie in Hollywood, that much he's made incredibly clear. He's an old-school Trekkie nerd who has it in his head that the only true measure of success is being billed on a major movie production, or knowing X star. The way he probably sees it is that the supposed legions of fans that grew up on his writing will flock to read his graphic novels because he's "That Sonic dude from the 90's" not realizing that most of those fans have either moved on, or hate his guts for trying to destroy the comics and paint every other creator on them as either incompetent or outright malicious with no evidence other than "I said it was so, therefore I'm right".
Also, I'll reiterate yet again because it's really important: He needs to market the damn book using something other than his twitter. This is the single most baffling thing about his project to me, just a seeming ignorance to the fact that without some way of getting the word out about his comic there is absolutely zero hope of it performing acceptably in any capacity. He doesn't have the benefit of working for a company that takes care of distribution anymore, he's fully indie and that means he has to get his hands dirty and sell merch on his own. Frankly though, I don't think he'll realize this until after he's already hemorrhaging money past the point of ridiculousness.
Look on the bright side: It's hard to have terribly written dialogue when your characters are busy frenching out in the woods
See this is why I think it's important to remember just what the landscape of comic books and Sonic were when Ken started. The 90's were a very weird time for comics, licensed ones especially, and in general both the art and writing standards were very low. Yes Ken was heavily responsible for introducing long-term story arcs and a much more serious tone, but that doesn't mean they were somehow good. He took a comic based off a fresh new game series with almost no story, and injected it with the kind of writing that made things like Youngblood and X-Force popular. That in and of itself isn't really a bad thing, but yet again it doesn't mean those stories were of a higher quality (Charmy and co. tripping balls on LSD after Charmy's friend OD's and dies in an alley anyone?)
