I'd add the repelling feature in rainbow six Siege to many games.

Namely ghost recon Wildlands and Battlefield. It would add a completely new dimension to the gameplay.

Chapter 3 to Metal Gear Solid V.

Small changes/features I'd add: 

FF XV - You can switch characters

Suikoden II - You are never forced to have Nanami in your party. 

Pokemon Franchise - Redistribution of stats for all (or most) pokemon, so that 90% are not as useless as they currently are. 

Zelda BOTW - Weapons can be repaired. 

Star Fox Zero - No motion control gimmick

Ratchet and Clank (PS4) - Higher difficulty option. The current highest diffculty is a lil bit easy. 

Horizon ZD - A bit more variety in machine enemies. 

FF X- Tidus does not exist and the main character is Jecht. (yes, the story is gonna have to be re-written because of this)

Well, besides myself, I know of only one other member who plays the game I'm about to reference, so this may be akin to screaming into the void. In EDF 4.1 there are 98 missions, x4 character classes, and x5 difficulty levels, for a total of 1960 levels to play in the chase to complete the game 100%. But the player can't see what levels they need in the lobby, and can only look at that information once they've joined a room. Less than ideal. This game, and every other game in the series also could use a dedicated run/sprint function. Thankfully EDF 5 introduces that feature.

That would be awesome. 
But also, if you change Tidus for Jecht and make the story fit that, that would be awesome as well. 

I just like Jecht as a character more than I do Tidus. 

I'd add a graphics options menu to every game who doesn't have it.

Lost Odyssey didn't have any minigame, come to think of it.

The hability to keep your level, gear and items on any Persona game. It's something basic that for some reason isn't there, and keeping the personas is not enough.
