I just think he was offended,and defended something HE made and nothing more. And us "lowly" customers keep his money flowing.
Don't get me wrong, I think it's OK for you to state an opinion and ask if there is bias in FM design for game purposes, especially based on information you've seen. I just think it's cool that the game designer would come in and address those concerns personally.
It sounded to me more like he was offended at the suggestion of bias in the FMs or fudging of numbers for the purpose of game balance. It is probably a pet peeve that he's had to hear over and over for... how many years now? While the tone may have been defensive, I think he simply wanted to nip that in the bud, which he clearly did.
Anywho, I think discussions like this, heated or otherwise, are good every now and again as they keep the integrity of the game in the open for those who haven't been in on such discussion before.
My positive take on the whole thing.
