The Kickstarter for Torment: Tides of Numenera is still pulling in the funds. They made a promise that designer Colin McComb would apologise for The Complete Book of Elves if they crossed the $2.5 million stretch goal.
I think this is a harsh thing to ask any author or game designer to do. However, some gamers thought The Complete Book of Elves made overpowered Elves. Others might disagree. The debate was whether roleplay disadvantages could weigh against rollplay advantages. This was a TSR product too; perhaps it was having the OSR debate years ahead of its time.
Watch the video, though, I think McComb rightly gives as good as he gets.
