Oculus just launched a pretty interesting Arcade project which is currently in beta for the Gear VR and the arcade already has 21 classic titles like Pac-Man, Sonic the Hedgehog, and many others.
While you can try out a trial of 20 minutes for every game, you will need to pay a certain fee for full gameplay, varying between $0.99 and $2.99. It's sort of like a time machine where you can just step in the past and play the classic titles from Sega or Midway.
In order to take advantage of Oculus Arcade, you'll need a supported gamepad like the Moga Pro or the SteelSeries. There's also no multiplayer gaming yet but it could be in the works. It looks like Samsung's virtual reality headset is gaining more and more content every week, having already received the official Netflix app with Hulu and Vimeo to follow.
The virtual reality headset also got a beautiful little game recently, and pre-orders are due to arrive starting with the 20th of November.
