Could be the christmas aftermath, but I'll concede that this hint was quite cryptic and I'll add some more. You'll have to be pretty hardcore to know that first one. There's this certain person that posted 26 posts, no, 1 post (ninjad ) ago though that is as hardcore in this as me .

Game #5

This game features a hidden track of music after the regular music loop if one waits long enough inside a certain house.

The game features many cameos of characters from another of this publisher's franchise. Even one of the main characters show a canny resemblance to a famous character. In the later stages of the game, this is somewhat justifeid by a plot point.

#6:

Second time this happens:

- Liquid!

- Sssnake!!

SECOND HINT:

Playing this game on your birthday, while having input the data of your birthday into the game, would make the game congratulate you via several nodes you are supposed to access throughout.

Hint fot #5:

72 hours.

Majora's Mask I presume .

Wouldn't know the others though...

That's...actually an acute guess, but it's incorrect. I should have especified that it is a seventh gen game!

#6 Metal Gear Solid 2: Sons of Liberty

#5 hm, no idea if it's not MM. Very wild guess: GTA V

Bingo the #6. :)

#5 is not correct, though!

Sad, but it would have been epic because it generated $1 billion in 72 hours and we're on a sales site.

EDIT: nah, I was too curious and googled it and searched your 2013 list, but that's too lame. It was your #15 last year.

That'd be right :P

A raven and Ian Holm... Ian Holm is Ash in Alien... Raven software maybe, but as far as I know they didn't make anything that has anything to do with either Ian Holm, Alien or the Tolkien universe as the actor is also obviously Bilbo Baggins...

I went to the Battle of the Five Armies a couple days ago and it's still on my mind... There's a place called 'Ravenhill' there, combined with Ian Holm as the titular Hobbit I'm going to randomly guess...

LEGO The Hobbit.

Though I don't exactly believe I came to the right conclusion here, I'm getting rusty in these last days .

All those guesses, and "RavenHolm" never crossed your mind? :P
