I was going to guess Inferno...but I had to look up weither or not that was even in the game - but when I recalled that there was Pandemonium.
Lets... see...
Find me around the world,
and I'll let you learn about him.
Grease might cover me at a house,
A monkey may also be around.
I can be at the house of an artisan,
who doesn't want to help the one who creates sculptures.
Where I most assuredly can be found.
Is that guy going to shut up?
Please, stay the night here,
You've saved a young one!
A bit of searching for this ship - you'll find me,
There on the floor - but keep the location of us a secret.
I might be six feet under,
You can have this - read it please.
I can be found in a home for children that a kind matron runs,
who have lost their parents - the war must be stopped.
Beat the owner at a game - you can retrieve something,
or you can stay an pick me up.
Our fountain is in front of our best hotel,
you can read this if you want.
Oh, dear! I hope you didn't eat that fish!
Please stay a night - you can read this.
The train comes and goes because of me,
You can read this instead of leaving town.
Do you smell the salt in the air?
If not, you can read me at the local hotel.
Centered for no reason.
You can solve the bonus is you want to - but it has no relation to the riddle above.
Bonus:
If you have one too many to drink,
You might see an array of lights instead of me.
What is the name of this location?
You might be more interested in the station behind this place.
PS: The official riddle might be a bit difficult.
