You can name it meth? That's depressing. Weed isn't even that bad in comparison.
Especially considering, in Tolkein's works, "weed" refers exclusively to tobacco, or a suspiciously similar substitute.
Nintendo seems to have forgotten that hardcoded censors are pointless given that people will either find out ways of bypassing them, or will use words that the censor doesn't object to despite them possibly being worse than the censored words. Softcoded censors always are better due to being dynamically changing based on the current vocabulary...too bad Nintendo doesn't believe in updates! XD
For what it's worth, Satan wasn't even originally a bad guy. In fact, Ha-Satan was originally entirely subserviant to YHWH. It wasn't until the New Testament came along that he was turned into a bad guy.
