For my first "VR Party" I've decided to give each person ~25 minutes with a total of four games plus the SteamVR tutorial:
1) SteamVR Tutorial
2) TheBlu: Whale Encounter
3) Audioshield
4) Irrational Exuberance: Prologue
5) Tilt Brush
Any thoughts from people who have demoed stuff? I'll be having about 7 people try it so this gives everyone a decent amount of time with the Vive. I might want to swap out Irrational Exuberance but I'm not quite sure (maybe something from The Lab). Job Simulator would be great to add but I think it benefits from a more extended session.
I'd swap out Irrational Exuberance as I've noticed it gives some people a bit of motion sickness and dizziness.
Try the archery game from the lab. People seem to pick up the controls quite quickly and have fun with it. Secret Shop is also an option if you are looking for a more passive experience.
If you don't want to swap out IE, then at least give them a fair warning before trying it. Nothing is more off putting in VR than feeling sick.
