I just tried out and finished one playthrough session of ACA Fatal Fury 1 for PS4.
This game even at level 1 difficulty is so hard as hell.
The last two fights especially.
Geese Howard - the final boss - makes all the Tekken bosses child's play in comparison.
Like how the hell do you give a guy who already does killer combos and infinite long range special spam - the ability to counter all regular attacks - do a low kick, he grabs and throws you, do a jump kick, same thing, do a punch below, same, punch straight at the face, same, punch from above, same.
Literally had to beat him by grappling and throwing him. (Because doing specials in this game for me at least was a pain)
