Did you ever ask yourself what would happen, if you mix the characters of Persona with the gameplay of Etrian Odyssey? Well, we know what happened, it is called Persona Q.

Mixing the labyrinth exploration of Etrian Odyssey, with all the little secrets, events, traps and so on with the style of Persona was an incredible idea. This works as a great dungeon crawling RPG. And with the level design magic of Atlus, this is a winner.

You start off from a cursed high school which gives way to a dangerous labyrinth with strange monsters. But with your party of chibified highschoolers from Persona 3 and Persona 4 you face these dangers. This is in the end another great game in 3DS excellent library.

I really need to catch up, so hints for the games outside of the TOP 10:

#15: Day of the Tentacle guessed by The_Liquid_Laser

#14
Deep in the labyrinth is a ... waterfall?

#13
You can be joined by a mighty warrior who talks to his miniature giant space hamster.

#12
Cooking under the moon.

#11
This DOS game set standards for the time with voice acting.

I love seeing Day of the Tentacle in lists that aren’t mine. Personally, I still prefer the original Maniac Mansion (and gosh do I wish they’d do a modern remake, updated with 3D visuals and maybe even VR!). But I think this kind of games have more chances to be mentioned among older gamers... I played both earlier mentioned titles on old ass PCs (Commodore 64 and Pentium 100MHz, respectively) during the late 80s for MM and mid 90s for DOTT... Many of you weren’t even born at the time. ?

10. Is correct.  
9.  Is correct too, but I just realized S.Peelman already guessed it.  (My fault for giving more clues.)

The others are incorrect.

12. Breath of the Wild?
11. I'm guessing Maniac Mansion mostly because I don't think you are a Wing Commander guy.

Breath of the wild is always guessed on the first hint. #11 is wrong.

There it is, that's the one!

This feels like a stretch but Dark Souls?

No, Mnementh was on the right track.

15: Yes. Well, not exactly the title, but almost, you’re in the right franchise.

14: That one could have worked, but I’m talking about another game.

11: No, different series, different genre, different everything.

Yes! Very good, pretty obscure game.

The only game not guessed yet, so here's a second hint:
#7
-The male lead is a former Enforcer of an organization called Ouroboros, he just doesn't know it until the end of the game.
-The female lead is the daughter a renowned former soldier turned Bracer. She wishes to follow in her fathers footsteps as a bracer, setting up the story for most of the game.
