For example, comparing Resident Evil 2 today with Resident Evil 2 archived on March 2014 shows that the March 2014 version had links to 23 similar games, 16 characters, 14 locations, 166 concepts, and 51 objects, while the page today has links to 14 similar games, 14 characters, 2 locations, 34 concepts, and 15 objects. And this matches my memory of the page before, where I remember it having a lot more links than it does now. Looking through the history page, none of the edits since March 2014 show any removal of these links.
A few examples of these missing links include locations such as Abandoned Buildings and Police Station, concepts such as AI Companion and Backtracking, and objects such as Acid and Ammo. And when looking at the history pages for these articles, I can't find any edits showing the removal of Resident Evil 2. It makes me wonder if there was some kind of bug that removed those links?
