VR arcade.
Buy some Vive headsets & gaming computers. Have a Roomscale space to walk around, setup a bowed plank for Richie's Plank Experience, build a few different sittings setups using OpenWheeler's budget frames (HOTAS, flight sim, racing sim, etc.). New England gaming prices are crazy...just look at the success of Dave & Busters, Nomad's, Sonny's, & even stuff like Brownstone Park and Lake Compounce. Charge $10 or $20 for a 30-minute VR session. CtrlV's arcade is $20 CAD per hour of VR time:

Add in some sweatproof headset covers & padded walls for Roomscale & you're all set!
