And believe it or not, that Top 10 List is called "The Top 10 Cool Religions in Video Games"!
#6. The First Church of LeChuck, Orthodox in Escape from Monkey Island
To those, like me, who have wasted their early childhood in the satanic industry of video games playing the games published by Darth Vader, and are already a fan of Monkey Islandian humor, the very idea of a church dedicated to LeChuck is so cool that would make it on this list. Add normal LucasArts (the name of Darth Vader's company) humor to the mix and the result is irresistible.
The church is ran [sic] by [a] priest called Allegro Rasputin (historical allusion) who's killed by LeChuck. Normal ghosts would haunt LeChuck but instead he builds a church and starts worshiping him. He writes him a bible which Guybrush dubs "the most unholiest of bibles".
They have a bit unusual way of marriage. There's a river of lava flowing through the church, and the couple should take a boat ride and... die. Then, they can marry as ghosts. Something like, instead of "till death do us part", "since death do us join".
LeChuck is the savior. Guybrush is Anti-LeChuck, and his name shouldn't be spoken. When Guybrush points that he's Anti-LeChuck the priest reminds him that "The Anti-LeChuck is three meters tall, [and] has a prehensile tail, a forked tongue, and the number "1138" stamped on his forehead."
They believe that LeChuck and Elaine should marry, and they "don't recognize Elaine's blasphemous marriage to the Anti-LeChuck."
Darth Vader is one of the greatest humorists of all times.
