Been a decade since this game has come out now have the games become more difficult as the years go by or have they become harder thanks to secret bosses,Demyx, Terranort,and even nice guy Zack?

None of the KH games are that hard imo .Unless you play on critical.

nope, theyve become to easy... I beat KH3D proud mode in a day and about 7 hours with the secret ending too

On Critical there bitches to beat otherwise they are just fine. God I still haven't beaten that damned Mysterious Figure on Critical with Ventus.

The whole KH series isn't that difficult but over the years I guess the games have gotten easier to play. I'm looking at you press triangle to win KH 2!~  But I mean at the same time they're not like extremely simple I guess. Critical mode always gives a nice challenge though~

All KH games are pretty easy . At least for me. (I have played ton of pretty darn hard games)

I still need to beat CM on KH2FM and Re:Coded, but I've played all the other games I own on their highest difficulty. 

Critical BBS: Piece of cake

Expert KH1: Surprisingly easy (maybe I've just played it too many times for it too be difficult any more)

Proud Re:CoM: No big deal

Proud Days: Not too bad, but more annoying

So far on Critical KH2FM: Not too bad

Critical Re:Coded: No idea

Critical DDD: HOLY FREAKING CRAP THIS IS THE FREAKING HARDEST THING I'VE EVER PLAYED WHAT IS GOING ON I'M GETTING ONE-SHOTTED BY NORMAL DREAM EATERS WHAT IS THIS

They were only ever hard for me on critical except for days' proud mode. 

KH3D tries to be KH1 in terms of difficulty.

Lately games have been going too soft,where is the challenge crash didn't have a difficulty choice and had it's challanges.

Depends... But I'm not the best Gamer... I am sadly better at other things

The only game I found really difficult was Re:CoM. I suck at using the card system. The only reason I beat it was by making my deck full of Sonic Blade Sleights and spamming it.

 

Days, KHI, and DDD offered a good amount of difficulty, or at least they suited my tastes.

Days... That survive-a-minute mission had me raging. I always died with a couple seconds left... Freaking Dusks... And that Zip Slasher or Lasher whatever... IT WOULD NEVER DIE.

Any game can be hard if you do it a certain way. Critical and Critical lvl 1 are the main things that are hard in this series. Also Terranort on Critical and  Mysterious Figure are the hardest bosses I've ever fought. So I think I can say that if you are either trying to 100% the game or play on critical mode, then KH is a hard series

I have found that usually the main game isn't a severe challenge with every single difficulty, but it's the extra/secret bosses that I have the trouble with.  I have yet to defeat VLS or the Mysterious Figure, and Sephiroth in KH has eluded me, but I haven't tried him in a while.  (I did die a lot in KH Re:Coded for whatever reason, though it was my first play through so I guess I have some sort of excuse.)

They are all pretty simple, imo. It's not that much of a challenge. Find a routine, and stick with it. Critical is a bit more challenging, though.
