I skimmed through this last night and had a blast. Thanks for hosting it, este!
This dude was way off on some of his game ratings, though. 
He was pretty harsh bitd.
In one of the threads here (possibly this very one), a UK member said that Gibbs acknowledged that he didn't have access to all of the games and, therefore, not all the reviews are based on actual experience, but fabricated instead (possibly using other reviews/fanzines/magazines as a reference).
Since this was no worse than the shenanigans pulled by mainstream magazines back then, and since I rarely agree with reviews in general (even today), this doesn't detract from Gibbs's overall effort. He should have simply omitted the score for any game he didn't personally play (he could have included commentary, even if it was merely "based on screenshots, this looks like a complex strategy game set in feudal Japan and colonial NJ..."
