Oh, and no serious player would give the slightest f**k about an engine's evaluation in a good game. The engine may "think" whatever it pleases, humans appreciate very different qualities.
Regarding myself, 99% of the games I love are severey flawed, which is simply a part of their beauty.
I think that it was done but I can't find the information. If we put all the GM' games of history in a good engine, what is the game that the computer will " think was the best, the most flawless?
