You can also RP that there is new endgame content added to the game. And that there's free-roaming in space.
Bit different with the end game content.
I'm not oppossed to SGR being put in the game. It just baffles me why people would plan their characters ahead on a feature with no date said on when it would be available. In fact, what seems to be the easiest way to add it, would be a new companion (and seeing as how there's a Cash Shop now, make it cash shop) all together.
Though if the only reason to play the game is the hope for SGR, then it doesnt sound like one enjoys the game at all anyways. SGR with an NPC is a couple cut scenes then done.
