That said, how will the Institute work?
You gain the ability to teleport there via fast travel from anywhere, and then fast travel back out to anywhere.
So, will I be able to circumvent the lack of fast-travel by simply going to the Institute first, and then to wherever I want?
Or will they make it so I can only teleport from the Institute to where I teleported in from?
Or perhaps only teleport to the CIT ruins?
Or only the place where I build the teleporter?
