Found a really small critter in No Man's Sky today. At 0.44m tall, the little spore guys I found floating around on a lush moon at the outer reaches of Euclid are nearly in the running for smallest airborne animal ever discovered.
I think it's very fun. I'm only playing on and off until NEXT drops myself. If I were you I would definitely wait for NEXT as the game currently has some issues that the NMS community at large hopes will be fixed.
