I think it looks like a pretty neat demo.
Within this Arcade you can experience, play, and enjoy your own personal little slice of 80's retro life.
The Arcade is built using Unreal Engine 4 as a learning experience for this powerful game engine.
Although it is built for VR, non-VR enthusiasts may also play this demo as a way of seeing what we can achieve in a short amount of time on UE4.
NewRetroArcade also works as a MAME, SNES, NES, and Gameboy emulation front-end.
