5. A No Man's Sky-Sized Galaxy
https://www.youtube.com/watch?v=RmsCJeh4YFg One of the biggest, most tantalising points from the initial E3 teaser was ex-Bioware man Casey Hudson describing an entire galaxy that would be available to be explored. He mentioned picking a planet on the other side of the solar system, and journeying there. Now initially this was packed away as nothing more than speculation, as although it might seem harsh to say, fans don't have the greatest levels of trust in the company following Mass Effect 3. However, since footage of Hello Games' No Man's Sky has emerged and it seems like it is actually possible for a development team to devote the resources to making an entire galaxy's worth of planets and assets, it's entirely possible that even from this early render footage, the tech being created for No Man's Sky will also help power something on the scale of Mass Effect.
