When it comes to Rhombus of Ruin, I've noticed that there's some holes in the info on this wiki. I can't do anything to help in terms of describing live gameplay (I don't have the game, or any access to VR equipment at the moment), but when it comes to plot-related things and "obvious" gameplay things, I'm going to try and rewatch some full playthroughs of it to see what I can glean. Stuff like the changes to the Clairvoyance ability and the presentation of memories in-game are two things I want to cover when I get around to this.
