well sf2 wasnt hard game even the boss bison werent that hard .
geese was cheap aswell but only on the ff days
in the kof he is balace and you need someskills to use him.
nightmare gesese is just power up ver. like shin akuma
except nightmare is ghost made of qi's
if akukma would do raging demon geese would do raging storm with lightnings from the sky and all.
reguler geese is like draw with akuma
but nightmare is another level for shin
expecialley in gameplay wise .but since everyone is die hard akuma fan then its a draw aswell
