Sure some are obvious. Many are not. Just for the hell of it. In case those who don't know. Explain yours.

I love food, I love anime, food wars is anime about food. I also love cooking and experimenting with new dishes. I also Shadow drop a new dish on work colleagues and they never get to have it again as it was a one off. My Instagram is basically food porn. Food everywhere.

So there is this game called Mystic Quest Legend in PAL regions, also known as Final Fantasy Mystic Quest in the US, that was developed and released by Squaresoft for the SNES in 1992 and 1993. It is basically a light-hearted version of Final Fantasy, much more streamlined and simplistic, with a very low difficulty and an easy to follow storyline. I played and loved it when I was a kid.

There is one scene in the game where you save a huge rotting magic tree from a demon infestation and once you managed to do that, the tree starts to walk and takes you to a new location on the world map. So while you ride the giant tree, some other trees in the background are placed in such a manner that they form the words "Go on, kid!". I loved that because not only was it a fairly heroic and releaving moment already, this little message was another form of motivation to keep you going on with all that world saving stuff.

When I registered here on VGC I had a hard time thinking about my user name but I remembered that I had written a walkthrough about this game not too long ago and decided to use this little message as my user name because I like it so much. And my profile pic is the artwork of the main character in this game.

Hey that's cool! I also like cooking and experimenting with new stuff. High five!

I don't have any sig right now, but I used to have sigs of Modest Mouse lyrics (different sigs with different lyrics). They are an indie rock band. The songs were Life Like Weeds and Parting of the Sensory. Still some of my favorite songs (those sigs were pretty recent but yea), the former being my favorite song for about 4.5 years now. 

And I mean my avatar is self-explanatory ... gotta rep the best Nintendo series   

My avatar is me dressed in Japanese festival attire (happi) blowing a conch

Awesome game series by the way, get the game!

Signature is a faction in a work of fiction I'm working on. Below is their official flag.

The blue represents the sky, the red represents the land, the middle is the nation that lives between the two.
