This. I have a couple of friends who actually met their partner on World of Warcraft in the mid 2000s. But I suspect it's a very small fraction of the “online” group, especially nowadays with dating apps being so prevalent.

I'd expect that the fraction is much bigger, actually. In mid 2000s the couples that met through online games were the "weirdos", "normal" people met online on dating sites. Today gaming is pretty much mainstream and while dating apps are probably a majority, it's now absolutely normal to meet people while playing games.
