Godzilla (Japan) (September 1988)

Yeah, I'm never sure if ads like this are actually trying to fool people into thinking they're part of the magazine or if it's just a stylistic design choice. 

Anyway there are a few giveaways.  This ads comes from a Famitsu, so we're using that as a basis for determining that it's an ad.

1. The page is unnumbered.  All editorial pages are numbered.  Ads are not.
2. Copyright/trademark info.  This ad is copyrighted by Toho, and there is also a note in the bottom right stating that "Family Computer" and "Famicom" are trademarks of Nintendo.  Editorial pages would not need this.
3. It's not obvious from looking a this page out of context, but Famitsu bunches all of its ads together rather than interspersing them throughout the magazine like a typical American mag.  So this ad is right in the middle of a 20-page section of advertising.

What's even more interesting/suspicious is the fact that a lot of the "ads that look like editorial pages" in Famitsu come from pages advertising ASCII games.  I say suspicious because Famitsu is published by ASCII.  Gee, conflict of interest much?  Would you trust a publisher's reviews of its own games?  Or appreciate the fact that they use the magazine they publish to advertise the games they also publish by disguising those ads as editorial pages?
