with Fighting is Magic, people suggest that because of the recent EVO event gave the game too much attention forcing Hasbro's hand
with Witchcraft, they have mirrors and a website. i posted it last page
TL:DR I'm slightly annoyed by how long it took for them to react to this stuff and prevent everyone from wasting their time making it only for it to be removed.
everyone is upset about it. people were really excited about Fighting is Magic (and it still has some possibilities of being completed, along with incomplete bases being released), people really enjoyed the Witchcraft series (again, mirror website).
there have been very detailed and informative posts about this elsewhere, explaining the situation perfectly. it's not entirely Hasbro's fault.
