Maybe I'm just naive but I don't really understand discontinuing things like this. Like, unless there are like 100 people using this, how can it not be possible to just leave this running at like 0.5% of its former capacity. Just leave up like 1 server, collapse all of the DBs into one, and let these few autists have their stuff.

It needs to interact with the main non-VR app unless they want to fully isolate it. Etc.
