Find your co-op partner (and your partner)

Your Steam library says more about you than your bio ever will. 2,000 hours in Stardew Valley? That is a personality type. A backlog of 400 games you bought on sale and never installed? Also a personality type.

How it works for gamers

Link your accounts. Steam, PlayStation, Xbox, Nintendo - we pull your game library, playtime per title, genres, and achievement data. Your raw library stays private. Only compatibility signals are used.

The matching engine understands gaming at multiple levels:

A game belongs to genres, has tags, runs on a platform
Playtime matters - owning a game is not the same as having 500 hours in it
Co-op vs competitive preference is inferred from your most-played titles
If you're on Steam and they're on PlayStation, cross-platform titles still match

Your hours played are the real signal

Two people both own Disco Elysium. Cool. But one has 2 hours (refund territory) and the other has 80 hours across three playthroughs. That is not the same level of interest.

Implicit sentiment: Less than 2 hours on a game you own? The algorithm treats that as a soft dislike (sentiment factor 0.3). You bought it, tried it, bounced. That is data.

Niche games > mainstream games

Mainstream

GTA V

85% ownership → NicheWeight 0.15

Niche

Caves of Qud

6% ownership → NicheWeight 0.94

The rarer the shared game, the stronger the signal. The algorithm uses global ownership percentile as the niche proxy - so indie gems, cult classics, and niche genres punch way above their weight.

What gets scored

Shared games weighted by ownership rarity

Playtime depth - hours invested, not just "owns it"

Genre overlap - roguelike enjoyers finding other roguelike enjoyers; JRPG completionists matching with JRPG completionists

Play style signals - co-op heavy libraries vs competitive FPS focus vs single-player narrative preference

Achievement patterns - completionist vs casual, speedrunner vs explorer

Shared dislikes - genres you both avoid, games you both bounced off. A mutual dislike of battle royale is a signal

Backlog energy - yes, we see the 400 unplayed games. No judgement. Someone else has the same pile of shame and that is a match

LFG but for life

"You've both logged 300+ hours in Baldur's Gate 3, you share 12 indie titles with a combined ownership rarity of 8%, and your genre profiles overlap 82% on narrative RPGs and roguelikes."

Not "you both like gaming." The actual receipts.
