Man I miss launching into space, the only sound my R2 unit chirping while I fire up the overloads, chart destination, and go Corvette hunting...
For all its flaws, SWG did some kickass things, one was Space. Just like crafting, many people only played the game for that part, never bothered with the ground after they got MAster Pilot, except to buy new goodies for the ship.
I don't have any hope that PVE will follow for GS. People mention time and complexity, but really it is CASH. PVP in space is low cost, all of it upfront. Build teh warzone. Done. It would take several orders of magnitude more money to build a decent PVE space universe.
