KH2, Sephiroth, it took heaps of day to defeat him, even i max everything, it all goes down to luck and skill. I completed 100% in KH1 and 2

FF12, i forgot which part, i think the boss got many sword, somehow i manage to win with one man alive... last boss is a breeze. i also completed everything. (still love ff series epic boss)

Prinny Can i be the hero(PSP): Last boss... is fuking hard, the button mashing make my hand sore....

Viewtiful Joe(ps2) i dont even wanna mention the boss, the platform already damn gay....

and one more hit aeroplane game, i never ever finish..it, it just too damn hard.. for normal mode, only the pro can win this game. lol i forgot wats the game call.... it is a ps2 game. I played easy to finish the storyline, shame on me...
