the dictator gives much more (somewhat surprising, as this might be an excuse to keep $66 for yourself and get away with it by claiming that both players still got equal money)

I don't think it's surprising - the modified version of the game increases the amount of fuzziness that each dollar buys, but doesn't increase the pain associated with spending that dollar. So the player will spend more dollars before the pain overtakes the fuzzy.

Thanks for the great write-up.
