Half-Life Alyx, will be a staple in the VR community. With the following that Half-Life already has, I'm sure this would be a fantastic selling point for arcades everywhere. I understand this might be difficult (with the concept of a story-driven game, in an arcade) however I believe given the right demographic, that we would have multiple people coming to experience what lovers of the Half-Life series have been waiting 10+ years for.
No Man’s Sky
Full VR support with motion controls announced as coming soon and (actual) multiplayer! https://store.steampowered.com/app/275850/No_Mans_Sky/
A game that takes strong inspiration from Half Life is definitely something to be hyped about. Coming sometime in 2019
Fruit Ninja VR
Great one for non-gamers with simple interaction. https://store.steampowered.com/app/486780/Fruit_Ninja_VR/
Blade and Sorcery
This newly released game is currently top of the charts for VR games. I have tried it and its like a much better version of GORN. This would be a great addition. https://store.steampowered.com/app/629730/Blade_and_Sorcery/
Looks very fun, 4 player co-op fixing your starship, like a more arcade friendly Star Trek Bridge Crew with Job Simulator style comedy and hand interaction. Supposed to be going into a closed alpha in a couple weeks so maybe the launch isn't too far off. https://store.steampowered.com/app/971650/Failspace/
Garden of the Sea
New game currently in early access from the devs who made Budget Cuts. Looks like an Animal Crossing / Stardew Valley type farming game, I bet kids would love it https://store.steampowered.com/app/1086850/Garden_of_the_Sea/
Would love to get Tilt Brush into our arcade, would be nice to have more art based games!
