I don't think repeated broken promises over a period of 15 years is due to him fooling himself, and common for programmers.
BTW, based on it's history I doubted it would be released this time as either, which I think was reasonable - I couldn't see what was so different now (a promised Steam, release is no guarantee). But I'm happy that it was released, since there was people waiting for it, and they seem to enjoy playing it.- So I'm happy for them.
I don't think I will buy it - my backlog is full of games I want to play. And I have to admit, to some degree, some of his activities on the net do play a role. I don't say it's wrong to buy his game for that reason, but it does affect my feelings, my enthusiasm for the game. I also think that some of his claims about the qualities/importance of the game and his own qualifications is a bit … exaggerated, which makes me a bit wary. Then again, I'm not sure if he's serious or just joking.
As for the price - if I wanted the game, I wouldn't mind the cost. To me, the content would be the important thing, not the production values and dated graphics/interface. I do however think he would make more money if he lowered the price, but that's perhaps not what's important to him.
