#20 (Nier: Automata)

-You can eat a fish to end things early

#19 (Final Fantasy VII)

-In something of a rare case, this game has an unreliable narrator as the main character

-The main character has confused his own past with that of his friend who passed away 

#18 (Dark Souls II)

-Shards of the primordial man became queens of the kingdoms

-Everything leads back to the first sin

#17

-Moving the statues out of alignment changes the world

-The game is divided into two parts, the dividing line between the two being the moving of the statues mentioned in the previous hint

-The statues represent three goddesses, known as the Warring Triad

#16

-All life on earth was extinguished around a thousand years ago

-It was brought back, but not in the way that was intended, thanks to one man's fragile ego and nihilism

-The main character is a clone of the person who came up with the plan to save life on the planet

Even more hints!

#25 - In my clue for #30, I quoted a wizard who went on a quest alongside a dwarf who shares his name with the protagonist of this sequel.

#24 - When they go Lo, we go Hy.

#23 - The poor N.American sales of this game were partially attributed to its lousy box art, but if that was the main reason, European and Japanese sales would have been astronomical.

#22 - This game launched a franchise that no doubt influenced a popular PS3/PS4 action-adventure series, which in turn inspired the reboot of the original franchise.

#21 - This game started out as an expansion, and ultimately became a full-fledged sequel, although that won't stop some fans referring to it as 1.5.

Guess I was just in time for these.

23) ICO?

22) Tomb Raider?

23 - ICO?

22 - OG Tomb Raider?

Man, I feel like I Know 21, but can't think of an answer.

[EDIT: Missed that post above.  Nevermind.  :( ]

Gonna try to nap another one of these:

16) Horizon Zero Dawn?

The Warring Triad sounds familiar as well, but can't quite put my finger on it.

24 - When they go Lo, we go Hy

A Link Between World

For 21 I'll throw out Super Mario Galaxy 2, although I don't know if fans ever refer to it as 1.5
