Ask HN: Which game's online mode is the best "3rd space" to find co-founders?

The YC cofounder thing looks like kinda desperate just like dating apps look.

According to your experience is there any lobby where something a bit more spontaneous can spur?

Even not solely confined to the startup world , but more in general in the niche of hustling to make money to blow on discretionary spending.

Kinda like a blackhatworld.com that spurs spontaneously from playing a game online with likeminded people
