This reeks of AIslop in terms of design and in terms of content. There's a Ko-fi link to support running the site but at no point do I feel like someone is running this because they actually care about these ratings. Just waterhose as many games and assign them some arbitrary label. Just a complete waste of time.
I literally built this for myself. I am a software engineer of some decades but this was definitely built with AI, both in the development and in the underlying engine that makes the assessments. I recognize that can be a bit of a polarizing subject so if that is a hard pass feel free. I personally wouldn't describe it as slop, it has a ton of considerations and the pipeline is quite complex, but you are free to disagree. It has a kofi link because it costs me about 60-100 bucks a month to run and personally its worth it for me, because I have already found a number of games I wanted to play through it, and I Will continue to host this as long as is reaosnable for my own sake. (Though with >1k games in my steam library I am not sure its particualrly healthy...)
