COM for me, both versions. 

The card system and I have never fully seen eye to eye. 

KH II FM, in my opinion: You don't level up for some of those boss fights, you get creamed. 

Re:coded for me, I never really got stuck because it was too hard, but some parts were frustrating^^ (Still like the game )

It's technically Union X, can't win if you don't pay

Re:CoM for me. I remember the GBA version being pretty easy, or at least not at a pace that required both the inherent mathematics and twitchy gameplay of the remake. Plus, those god damn minigames.

 

Still a fun game, mind, but hard.

Tough to say. I haven't found any of the KH games to be insanely difficult or anything, but each game and respective difficulty mode varies.

 

Like, I loved CoM back on the GBA, but found the transition to Re:CoM in 1.5 to be difficult the first time I played it. I think don't think the series is hard, but things like secret bosses and such are what makes the game challenging. 

Dream Drop Distance, i'm had a hard time trying to beat this game, but it's not the hardest.

Re:Coded I'm stuck on one mission.

I would have voted for KH1 Vanilla because you cant skip cutscenes in this version and it was often horrible to have to sit through a 5-10 minutes cutscenes everytime you die to a boss.

Overall of all the KH games i played i had the hardest time with 2FM because of the lvl1 challenge.

kh bbs terra sense all the secret bosses are near impossible with him

KH1/FM, Gravity is your enemy. To me, DDD was the easiest followed by KH2FM. The only challenges in either game were the secret bosses.

I'd say KHFM or Re:COM for me. KHFM mostly for 100% completion (secret bosses, wizard relic) and Re:COM... I just can't comprehend the card system.

Chain of Memories. I will never like that card system. Like at all.

Chain of memories because I feel like I am not able to play Sora to his fulllest potential and there are so many limits that I could not play the character right.

Chain of Memories on the GBA! I just never got used to the controls and it was very tricky and also the card system just made things tougher. However, I am actually pretty good at the Re:COM games. I don't know what makes the differences click for me with Re, but I just can't get used to COM as much as it's remake.

to this day, KH: ReCoM is the only KH game i have never beaten

tbh it depends on whether you're playing normally or if you're doing a higher difficulty/challenge

Like most things LV1 are gonna be pretty hard

But if you compared the Standard difficulty for all the games or something... idk

It's technically Union X, can't win if you don't pay

haahahaahahahahaah~

Kingdom Hearts Final Mix: Re: Chain of Memories- Sora's mode. Riku was less time consuming and more simple. It's going to be a pain replaying it on ps4 man....

Original CoM without a doubt. I attempted that game so many times and I still have not finished it once. One of these days I need to buy 1.5+2.5 so I can actually see what happens in that game.

KHUx hands down is the hardest game. Because

 

1) you can never technically finish the game

2) It cost multiple expensive microtransactions to actually enjoy the game

Chain of Memories on GBA. while the card system more or less functions the same between the GBA and PS2 versions, that dodge roll in combat was a pain. at least Re:CoM gave you a full 3D environment to avoid enemy attacks in. i had the hardest time trying to keep a safe distance from enemies in CoM and rolling rarely ever helped.

 

runner up might be KH: Chi. although i never played it past the first couple of missions. since it's a mobile game designed with in app purchases that impact gameplay, i would think the game would be designed to be difficult to a point that forces you to spend your money to progress. 

I was going to say Re:COM but once you figure the system out, it gets really easy. Like...REAL easy. It's just long because you need to get through the rooms and open the rewards rooms to get sleights and stuff.

0.2 for me because they strip you of key abilities on critical

None are what I would call hard games, Chi might be the most troublesome though, some of the later boss fights are ridiculous if you didn't spend hundreads of dollars to buy good cards.

 

Re:CoM is a joke, understand the way it's supposed to be played and you can go through everything the game throws at you without even getting hit once, Card break and sleights break the game hard and takes the fun out of it.

Chain of Memories for me... When I was playing it for the 1st time I raged so much and rage quited . Then I came back to it and somehow finished it. Hardest fight and where I raged the most was last fight with fake Riku, Vexen and 2nd Axel...

Terra took me 4 days of almost nonstop playing to beat at level 99 with all items and abilities up to that point on proud mode. Definitely the most difficult thing I've done on any KH game. Have never challenged the BBSFM secret bosses though.
