Exactly: this is what I've found with my younger coworkers. I played video games a lot when I was young, but it wasn't that much of a social thing because the internet wasn't commonly available (we had BBSes) and the games were all single-player DOS or console (NES/SNES) games. Now it seems video games are a social outlet for men under 30, and as you said it's what they talk about in person a lot too, unlike TV.
