The impression one gets from Arneson's own accounts in this book really leaves me with the opposite impression, that Gygax and the Blumes wanted it to work with Arneson but he was not willing to meet anyone halfway or apply himself. His post-TSR history is particularly telling.I’m not so sure.
I do think him and Gary clashed on many levels. And so, without much power in the relationship, he couldn’t get any traction.
I think much of the myth of “he didn’t do anything” about his time at TSR can be put down to: it was a VERY short time there and he was the kind of person that would clean toilets (work his but off in shipping) cause it needed doing. I think that soaked his time and drained his will.
But I must add that not only Gary had made similar claims about Dave.
