Earlier quoted context omitted.
Imagine if you could put on these futuristic goggles that immerse you into a virtual reality world where you could do things like cultivate a virtual farm with your virtual friends. Facebook already has this (Farmville), but Oculus would take this to the next level.
Farmville and games of like ilk are designed for intermittent play, in short sessions a few times a day. This doesn't strike me as a compelling use case for a head-mounted virtual reality display.
With virtual reality, any game could be made to be much more engaging.
