+1 for half life alyx with the index, shit is an amazing experience, the 1440p 120hz makes it feel super lifelike (only downside was the cord can get twisted sometimes if u walk around in it too much)
superhot is pretty fun too although not that many levels
there's also mods to make other games work in VR, my old roommate had GTA V in VR and that shit was super fun
i feel like the next generation of headsets will probably be cheaper/better, but idk if VR is really the future cuz i always got a headache/needed a break after like 30-45 mins, nice party trick to show your friends and mess around with occasionally tho
