Because said projects uses copyrighted material - characters
now - just using the same style as MLP
Quote: "Nope. If I change their names, they don't infringe copyright."
So youre saying I can take a whole game, rename it and everything in it - and rerelease it? No, see the characters - design wise are copyrighted.
from wikipedia:
Quote: "Scope
Copyright may apply to a wide range of creative, intellectual, or artistic forms, or "works". Specifics vary by jurisdiction, but these can include poems, theses, plays, other literary works, movies, dances, musical compositions, audio recordings, paintings, drawings, sculptures, photographs, software, radio and television broadcasts, and industrial designs. Graphic designs and industrial designs may have separate or overlapping laws applied to them in some jurisdictions.[16][17]
"
and no, thats not limited to wikipedia - that information is everywhere. Basicly, as soon as you create something - that is original and unique to some degree, it's in most countries automaticly protected by copyright. I imagine it works differently for works created in US.
But the main point is: Anything you make, that is unique - and original - is copyrighted. Thus - the design for those characters do stand under copyright law.

Whose eyes are those eyes?
