So is 5 Skyward Sword?

And 4 is Yoshi's Island? (baby Mario crying being the sound)

#6: Hint: At one point in the game the whole scope of the story suddenly explodes in size.

#6: Hint 2: A summit of extreme hight is where you realize that the adventure has only truely begun now.

I can see how the “wake another entity” part kind of fits with Skyward Sword, but that’s not what I mean. So, also incorrect.

4: Is correct, Yoshi’s Island it is!

Just working through the Zelda games here for number 5, hoping it's right. Ocarina of Time is my next guess, but I can't for the life of me remember a mural in that game.

#6: Hint 3: In how many games do you accidentally destroy the entire world?

#4: Hint: Aliens that attack our world come from another dimension that reminds me a bit of the mirror dimension in Doctor Strange.

Second hint for #5, and first hint for #4.

#5: The whole secret of the game is blatantly told on a mural halfway through the game, but when you first play it, you don't exactly realise what it means until the end boss explains it.

Hint 2: The mural was pretty vague about it, but the boss explains that beating him, would wake another entity and have far-reaching consequences for the land you're in and everyone that inhabits it.

#4: This game features the most annoying sound in the world. Guessed by drbunnig - Super Mario World 2: Yoshi’s Island

#4

• An age is slowly coming to a close once again.
• The sun god's fear caused them to stop the end once.
• The god's actions broke the natural cycle of the world, putting it into an endless loop.
• When this game was being advertised the publisher heavily emphasized one very specific aspect of the game, effectively leaning into the reputation this game's spiritual predecessor had cultivated.

#6: Hint 4: The two most important characters have brightly colored hair.

#4: Hint 2: The first part of the name of the place the aliens come from is also the first part of the name of the game.

Correct.
