Though at this point it would be a bit much to ask for you to add on to the Tower, however a larger social area would be a welcome sight. One of my favorite things to do in the beta was to get around people and chill, compare armor and weapons, and just feel this strange sense of silent comradery (because no one could talk to each other) and just be around other people. Social areas like a bar or even a shooting range to test out and compare gear would be a great addition to the game. Perhaps an addition could be added later through either DLC or FLC (free DLC) but I definitely wouldn't expect that at launch.
Im pretty sure PlayStation users will get early access to a day spa area on launch day where their guardian can get a full body massage and a facial. Xbox will have to wait 6 days.
