I have read countless people (search reddit) say using VR devices outdoors in direct sunlight destroys them. Just keep that in mind I guess.
But hasn't it been confirmed PSVR2 wil get Alyx? Sony said they're making it compatible with PCs, so it will get everything PCVR has if so.
As far as games for the kids, the normal stuff Beat Saber, etc seems to be the go to. Depends what they're in to mostly. More hardcore games like AC: Nexus or Asgard's Wrath 2, RE4, or lighter sports-like multiplayer stuff like Walkabout Mini Golf or Table Tennis etc. There's some popular FPS choices too, but I'm not super familiar, and you also can sideload games like Doom/Half-Life, etc.
