Remake So It Doesn't Suck?

[Azuren]

Kingdom Hearts: Chain of Memories
The card system just doesn't work. It doesn't. It's stupid, and it allows to to cheese bosses by stacking level 9 cards and popping 0's to stop enemy ultimates. It's just bad, and using a traditional combat system in place of it (keeping the cards for doors) would make more sense. It would also give reason to actually program real areas into the game rather than recycling the same ten templates onto different world palettes.

Kingdom Hearts: 358/2 Days
Every problem in this game (from a functional standpoint) could be fixed by just not being on the DS. The DS can't handle full-movement polygonal games like this, and it shows in both the graphics (which were admittedly amazing for DS) and camera control.

Kingdom Hearts: Re:coded
Same issue with Days: wrong system. Would benefit greatly from a remake on literally any current dedicated gaming system.

Literally Any Numbered "Final Fantasy" Title
Especially PS1 and prior, Final Fantasy titles could all do with a bit of remake magic. I'm not saying they all need to play like FFXV or even close, but titles like V and VI could do with an updated script and game mechanics.

Legend of Dragoon
Just so we don't have to hear about it anymore from @BraLoD
