About imho.run
imho.run is a Steam game recommender that combines collaborative filtering (ALS / iALS / EASE / LightGCN) with content-based scoring over genres, categories, Steam tags, developers, and publishers, plus AI-extracted gameplay vibes from review text. The lists you see here are generated in seed mode — anchored on Heliopedia— so they answer the question “what plays like this?” rather than “what fits my library?”
