When I say this, I mean it sincerely: No Man's Sky is filled with a sense of awe and discovery that Spore should've owned back in 2008. There's that delicious mix of the prehistoric and the futuristic, a seamless transition between terrestrial exploration and interplanetary dogfighting, plus you're flying an X-Wing-like fighter in and out of various planetary atmospheres; no loading. The sky is no limit.
No Man's Sky will introduce its procedurally generated worlds to PC and PlayStation 4...someday.
