For those who think that only first-person shooters have to face problems when it comes to censorship can easily be proven wrong. Even the NES porting of the ICOM PC adventures Shadowgate, Déjà Vu and Uninvited (ported in this chronological order) had to be altered for Nintendo's "Toaster" (as it's sometimes called by fans).
This is a comparison between the censored NES version (released in 1991) and the uncensored PC version (released in 1988).
Religion / Satanism
The address on the envelope was edited out for obvious reasons. However, the censors from Nintendo seemed to have done quite a sloppy job since you can still read that it's adressed to "Mister Crowley" (=Aleister Crowley, the founder of modern Satanism).
All pentagrams were edited out of the NES version.
In the PC version there'a a carpet with a pentagram on it in the lobby. In the NES version, the pentagram was replaced by a regular star.
On the book of spells in the next room, the pentagram was replaced by an unidentifiable symbol.
A small pentagram item (slightly highlighted on the screenshot, since it otherwise can barely be seen) in the NES version was replaced by a ruby.
All crosses were edited out of the NES version (the wooden cross in the church which you need for the battle against the final demon was replaced by a goblet with holy water).
Text / Violence
Several texts and grpahics were mitigated for the NES version.
Death by "Scarlett O'Hara"
Undead Inside the Jail
Censored Text and Graphics
Suicide with an Axe
Mauled by Dogs
The Ghost in Front of the Labyrinth
In the PC version you're looking for your younger brother. In the NES version you instead are looking for your older sister.
Only in the NES version there's a little easteregg - a reference to ICOM's Déjà Vu. It's unclear to why this easteregg was not included in the PC version.
