In Regards to VR and this is to everyone!
The team have stated either it wont be done or it will be done but it will take a while like a YEAR! VR although very popular, I only know a few people who actually own a VR headset who are in the TU Discord/Community.
In Regards to Waterslides
Yes, I would like to see it come back but the problem was with the Lobby 2 Waterslide was that no one used it, yes in the Beta people including me did but it acted alot like the pool in Lobby 1, people used the Pool in Lobby 1 when it was about to shut down or there was some event.
