Clearly I know nothing of Harry Potter, but I think it would have been a lot better to have kept the name of "Philosopher's Stone". Who really doesn't know what it is, even in rough detail? It's way more epic than a "Sorcerer's Stone".
The Sorcerer's Stone can just...I don't know...do your laundry for you, but the Philosopher's Stone can turn metal to gold and give you immortality!
