Tsukihime Surprise. Others?

[Freelancer]

I'm sure everyone already knows, and maybe this is pointless to post, but... I have to tell SOMEONE, and this is the only place that cares even a little about VNs.
It was about 1:14AM December 25th at my house. For a reason not pertinent to the story I decided to open up Tsukihime. It started to go through the usual start up sequence when suddenly, Ciel-senpai appeared on the screen in a red Santa hat saying "Joyuex Noel!" Then it went through a whole thing about Christmas being a time to spend with family, ETC etc etc...
Needles to say, that scene blew my mind. I had no idea that was there.
When I originally started typing this I had no point other than just saying this, but now it's made me think of a question...
Are there any others with this kind of surprise? Or perhaps something different?

Wow! That's really neat! I didn't know about that, either!

Since I'm not the only one who was unaware of this I feel I must provide pics. Proof.


See? That happens right after it says "Type-Moon" then "Mirror Moon" Then the "Teach me Ciel Sensei!!" Starts.
Once you finish it, it brings you to the main menu, but still.

Really neat surprise from creators! I love when they do such things. Honestly, more games and visual novels should have such bonus content

Wow! That's a cool bonus...

Just curious, will setting your PC time into December 25th on your own also unlocks the bonus?

I imagine so...I wonder if it does that for any other day?
But I agree with IceD, I love it when there are these hidden surprises.

For the curious, someone posted a vid of the egg here: http://www.youtube.com/watch?v=P6npWLyudTo

I think Tokimeki Memorial did something where you get different welcome voice clips on certain holidays.

This is not a VN, but SEGA's DS game Feel the Magic: XX/XY have little bonus too. Only a voice, but it's still pretty cool. When it's Christmas, the heroine will greet you "Merry Christmas", and so on. Besides Christmas, I think it's also activated on New Year, Valentine, and your birthday (depending on your birthday that you could input in DS menu screen).

Haha - I saw that as well
Also I think all of AliceSoft games (Rance, Big Bang Age, etc) have a small intro where their mascot is in a season-themed costume (e.g. in autumn she is sweeping leaves in a miko dress
