If it’s any help to you, the game coverage on giantbomb is getting worse as well. I started helping to update their wiki at the same time I started using grouvee, around 2015 - purely for self-serving purposes, to add games that are missing in my grouvee backlog.
Back then they already had most games I was looking for, and I only needed to add a few smaller ones. Over the years this has shifted a lot, and nowadays I have to add a good 35%-40% of my backlog mysfelf. At any given time I have a good dozen or so games that I need to add to their database and just procra… am too busy to do it.
I’ve entirely given up on VR games, because other than the biggest releases I basically need to add every game I want to play myself.
I’m not entirely sure if the number of people willing to contribute to giantbomb has gone down in absolute numbers, or just relative to the growth of the games industry in the last decade, but it’s definitely noticable that the coverage on the site is way lower than it was back then.
