This is what I came up with for the values of the various games.

I couldn't come up with a mathematical formula that seemed to put everything in its right spot, so this is kind of subjective.

I considered mostly the "importance" of the sport and "importance" of the game, the length of the game or season, and the frequency required to play (daily, weekly, or one-shot).

I also have to go back and check; I know I left a few games out.
