Steam recommender with social graph and vector addition

A long time ago I made and posted a social graph of Steam games that showed communities of games where people who played game A also played game B.

I had some spare time so I remade this as a live webapp that does recommendations based on your steam profile or your favorite games, lets you explore the map (and see your games on it), and also lets you add games together - e.g. "Stardew Valley" + "Five Nights at Freddies" lands close to "Terraria" or "Don't Starve Together"

I was hoping this would be useful for people here! I'd especially love to get your feedback and see how good or bad the recommendations are for you.

(Mods said this was ok to post here)
