Friends series remake

[Ceenab]

My vague understanding of copy legislation (which differs globally) is that all aspects need to be about 10% different from the original, so 10% different names, 10% different faces, 10% different clothes etc. etc.  But this is not legal advise, just what I've been told by other performance artists (not game makers or film makers).  At least you asked first!  Very considerate and good conscience!
