Michael Caine's famous words on his films "I wish they'd remake the bad ones instead".

A few games that should be remade to be better but to the person who said Hollow Knight I'll fight you on the street or in a PPV ring over that one:

Galleon - Toby Gard (Lara Croft and TR creator) the smug prick said this game would buy him a sports car for every finger and toe he has fair to say it didn't go to plan, you could see the ambition in the game but the execution was lacking and technology at the time didn't help, it can be done properly today though.

Geist - I feel this game's concept has huge potential even though the game was about average.

Blinx - Again concept with potential but poor execution.

This, but I would go much further.  Get better script and voice talent, bring out more interesting plot. Redo everything until the more open area. Fix battle System. Add cities... better music... etc. etc.

That's funny you know, one of his earlier films, The Magus, is based on one of my favorite books of all time. The movie is absolute trash, unfortunately.. a remake in the right hands would make for an incredible movie.

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

Final Fantasy XIII

Why? It's my most hated game and it's in my all-time favorite game franchise (VI is my favorite game, and VII, X, and XII are all in my top ten of all time and VIII/IX is just outside my top ten while IV/V are just outside my top 25).

To fix it? I'd drastically change its battle system. I kinda like the idea of paradigm shifting in theory, but in practice it took virtually all control out of the gameplay, leaving it as an example of style over substance. The only real agency the player had at any given time was what job a character took and at what time. that's it. so, replace the paradigm shift system or alter it so that you can PROGRAM your characters like in FFXII. Imagine you can create your own classes, so instead of 'sentinel' which is all defense all the time, imagine you could make your own 'Sentinel' which was a combination of attacks and defense. Focus on buffing and aggro control, but still attack once your skills take over. Also, make the battle system so that you don't automatically get a game over when the main character dies.

Man, XII's battle system was just so much better than XIII in virtually every way.

And fix the narrative so that you don't HAVE to read datalogs to understand who people are. There's nothing wrong with supplementary content being relegated to an in-game encyclopedia, but it has to be supplementary and not primary information. The fact that I had to read the datalog for like 70% of the game's plot and character development was, on its own, the greatest failure of narrative I've ever seen in a game. Dark Souls's labyrinthine world building is better by a country mile.

Also, I think a bit more nonlinearity would go a long way. Sure, I don't mind linear games (FFX is one of my favorites),b ut there's a huge difference between a linear game that gives you many branching paths and some exploration along the way and a linear game that is basically an RPG on rails. A walking simulator where you occasionally get interrupted by battles you have very little control over that last forever.

so yeah, three key (but significant changes). Change the battle system, fix the narrative, and add some more nonlinear elements and exploration/side questing throughout instead of just chapter 11.

It'd still only be an okay game and not great, but that'd go a long, long way.

seriously? did we play the same hollow knight? hollow knight has propably one of the best combat systems in it's genre. compare it to castlevania and every semi clones of it where you just got 1 attack, 1 throwing attack and a backslash. one thing which could be remade is the map / travel system, it had way too much backtracking and not enough shortcuts.

Life

I mostly agree with this.  I think, somewhere in the beginning, they actually had a good story idea, but it was executed terribly.  The dialogue is bad and I feel kind of "meh" towards most of the characters.  On top of that they don't let you control which characters you use in the beginning.  In FF6 this was ok, because the story was really good, but in FF13 they take away control just so you play through a really bad story on top of that.  Also I agree there needs to be cities and stuff.

However, I find the music to be quite good.  I don't need that changed at all.  I also find the battle system to be extremely fun.  It really sucks at the beginning, but once they let you pick your party and how your characters grow and actually put some challenge in there, then the battle system really shines.

I know some people just hate the whole game.  That's not me.  I am in the camp that there is a really good game on a drawing board somewhere, but it was executed poorly.  That is why I want it to be remade.  There is so much wasted potential there.  I really, really loved the game a lot once I got to Gran Pulse, but it was just a hell of a slog to get there.  As much as I loved the last 80 hours of FF13, I don't know if I will ever play through it again, because I just don't want to endure the first 20 hours again.

Yeah the back tracking per say wasn't bad but the the inconsistency of fast travel locations was, my only other main gripes are some of the platforming design were tediously designed (some parts intentional like the white palace) to be frustrating and they need a more consistent check point system as like with fast travelling locations they were inconsistent an example being in the Hive where the is only one in the whole area in some remote part with the last bench being in a previous region.

Other than that it's one of the best Metroidvania games around imo to the point it can stand with games even in the two series that created the genre.

That definitely would've been a good idea. Metroid was an Open World like-game without the incredibly obscure puzzles. 

Metroid was an amazing game even back then. I played it and Super Metroid multiple times and enjoyed before. I think the two games are different in the same way Ocarina of Time and The Original Zelda are different. I think Metroid Prime 4 would be wise to take some inspiration from NES Metroid in the same way Breath of the Wild did with Zelda 1.

Castlevania 2 actually fun if you know what to do. Thing is that most people have no clue what to do. Once you start playing it and understanding the system it becomes a wonderful idea. However, it stills feel incredibly limited compared to the later games making it harder to enjoy fully. Though you have to be happy about the later Castlevania games since they are more like Simon's Quest than the other ones. 

Also, Castlevania 1 and 3 are hard but they really don't start getting really stupid hard until near the end. Dracula's Castle in 3 made me go crazy with all its enemies and bottomless pits. The darn game had no mercy. It didn't help that you only had 3 lives to get through the stage AND beat Dracula. (Who has 3 forms that you must be perfect with. Did I mention that the last form has bottomless pits? Ridiculous! )
