There does not seem to be any correlation between game play and Hall of Fame score.

Length of game or difficulty do not seem to have any reward of points.

The high scores seem unconnected to anything under my control.

I finished an Insane Map game the other day that took me about 40 hours to play and received 12 points.

I have seen that a Hall of Fame can be an exciting addition to other online games but apparently not in GC3.

Apparently my best policy seems to be to ignore the Hall of Fame in GC3.

Sad.
