Read what Zuckerberg had to say when Facebook bought Oculus.[1]: "This is really a new communication platform. By feeling truly present, you can share unbounded spaces and experiences with the people in your life. Imagine sharing not just moments with your friends online, but entire experiences and adventures." He's talking about VR as a social medium, like Facebook.

Sort of like Second Life. Second Life has supported the Oculus Rift since late 2014. Nobody cares.[2]

I can see using one for FPS games, but beyond that, it's not that compelling. There's still no killer VR app.

It's not about hardcore gamers if you mean FPS or something. But it's not aiming at the middle of the market. It requires a high-end PC just to drive it, and it's an expensive peripheral, so it really can't be "mainstream". It's about people who are the most interested in VR gaming.
