It's not a 'lettertype' (it's a 'font'), it's a form of text called Word Art, which basically let's them use a normal font like Arial, and change it into a type of picture that has effects on it. It can be glittery, burning in fire, covered in mud, and many other things as well.

Yeh I know. but the shape of the letters itself is what I am looking for.
Not the 'decorations' and stuffs about it..

Haya everyone.
I was wondering if someone knows where to find/dowload the official lettertype they always use of Sonic games.
for example "Sonic heroes"
that title also uses those letters.
