I wish there were a way to search for people whose libraries overlap the most with mine - meaning we share the highest number of games in common, while having the fewest that are different.

Right now, I often end up talking to friends who have no interest in the games I play (and vice versa), or people who only ever play a single title. What I’d really like is a way to connect with players who have a library that closely matches mine. That way, we’d naturally have more games to talk about, and they might even recommend titles I’ve overlooked. If our libraries are almost identical, it seems safe to assume our tastes are, too.
