I really am surprised a VR project was ever considered. As someone who owns a Quest 2 and links to my PC to get games from Steam, I can easily get certain games that would offer a similar experience or if WB released an actual Potter VR game, then it would make the VR attraction in the park seem like some of those old DisneyQuest VR things.
VR is rapidly taking off in that every year or two a new headset is coming out that keeps pushing boundaries. The Pico 4 just came out and made the Quest 2 look way outdated and it's only 2 years old. The real problem with VR though is the graphics simply aren't there yet. There's a few games where they look real nice (Half-Life: Alyx, or the Red Matter games for example), but compared to console gaming, it's still going to take time for the graphics to work their way up into a headset, which I think, on top of capacity, was probably one of the biggest issues with the Potter VR attraction.
Sorry for the VR ramblings lol. I'm looking forward to whatever KidZone eventually turns into, just not expecting much and I think it's best everyone keeps expectations low.
