When Fortnite reached stratospheric popularity early last year, there were undoubtedly an awful lot of VCs on the sidelines looking enviously at the massive platform and wondering what opportunities could be gleaned from its rapid rise.

Epic Games went on to raise later that year at a nearly $15 billion valuation so some of those investors decided to invest directly in the Fortnite creator’s continued ascent, but others have been looking to get in on the ground floor of new operations that are aiming to rethink the line between video games and social networks.

Today, Andreessen Horowitz announced that it’s leading the $16.5 million Series A of a stealthy gaming startup called Singularity 6. The startup’s ex-Riot Games co-founders claim their venture is less focused on building a button-mashing competitive shooter than it is a “virtual society” where users can develop relationships with in-game characters powered by “complex AI”.
