Immortals incaese in numbers.
Even though they should decrease because of "The game" they increase. ok, imagine highlander 2 did not existed which had a planet of immortals.
in highlander 1 there was only 2 immortals to fight.
in highlander 3 there was 3 immortals.
in highlander 4 there is somehow 6 immortals to fight
(i am not counting romirez in 1,3 and dunkan in 4th, as those they did not fought against)
Oh and did i forgot the watchers, who obviously were immortals too if they lived 5000 years.
So instead of "Gathering" there is even more immortals to fight every time.
whats next? a whole immortal state against McCleods?
