Bought "Keep Talking and Nobody Explodes" yesterday, to play with friends and family.
It's an absolute blast (no pun intended). Seriously, I've not laughed so much playing a game in years. I can see why there are some Wii / Kinect comparisons, but honestly, with the fun I've had playing Driveclub, RIGS and this, it's already got more use than either of those.
Realistically, you could recreate the game without VR by publishing it with a disc and manual, but even so, it's a great experience.
I just wish, WISH, I didn't have to fuck about unplugging and re-plugging cables every time I want to play a VR game. If you're making a console that you're labelling as "premium", and a VR headset that, when combined, costs £700, how is it acceptable that I have to pull the console forward and pull out / rearrange cables every time I want to switch from a 4K game to a VR game? Get real.
