i wanted to ask for u which was the toughest game and the toughest boss for me the toughest game was kh re chain of memories i mean it wasnt that hard but i didnt like the card system and the toughest boss was xigbar kh2 cause every time wat happened was that id overused the forms and i turned into anti sora

nah just normal COM was the hardest, the 2D did my head in... the hardest boss for me, not having any FM's or RE:COM, has to be Sephy purely cuz I needed to get to level 99 and reflega abuse him =3 haha

If you choose the sword at the big columns during roxas's 7 day journey, you will receive second chance at lv 75., but you can receive it earlier or latter from the sheild or wand, and by the time you are at that lv. you should be strong enough to be sephy, i did it, but i think i had ultima weapon

 

but i don't know what rank you are doing it on, if you are doing it on proud, then you really want to be lv. 99

The toughest boss is without a doubt Sephiroth. If you are weak enough, one blow is enough for Sora to pass out. He's tougher than the actual final boss.

Overall, I think that it's pretty hard to say since a number of us haven't really gotten our hands on any of the remakes other than RE: COM. Though for me I would say the hard of the games is both COM and Re: COM, mostly since the whole card battle system didn't appeal to me too much. As for the hardest boss I would have to say Sephiroth from KH1. Facing him again in KH2 seemed like and easier fight to me.

I've only played CoM and Days, to be honest.. Pretty much anything is hard in CoM due to the horrible gameplay, so...

 

LEECHGRAVE.

I hated that thing. Took me a long time to beat it.

Xion and Leechgrave should have swapped difficulty.. Xion was incredibly easy. I only died once, and that was in the final battle, and was my fault due to wanting to wait to heal so I could use a Limit Break.
