I want to put a more simplistic suggestion for calculating HoF rating. It should significantly improve the current system.
Assuming game has N players. 1 winner (2 in case of tie) and s ( a. Winner gets N*W points
b. Survivors get N/S rounded down points each
c. I will accept corrections to any of the old games with a list of survivors. For new game this entry would be mandatory.

W is a factor of how much we want to reward winning a game. I suggest W=1.
S is a factor of how much we want to reward sticking to the end of a game. I suggest S=4. Meaning that surviving 4 N player games count as one win!

This solves problems 2 + 4 of current HoF. #3 is partially addressed since surviving in games counts.
#1 can be addressed if we start tagging a games as NewB or Vets. Then NewB will get, say, 3rd of the points.
