No Man's Sky is free-roam adventure on a galactic scale. Tens of thousands of light-years of possibilities. No two systems will be exactly alike, and each planet or moon I visit gives me a reason to explore it, even if only to look at cool stuff. Also, it's easily mod-able. Hello Games has put A LOT of love and hard work into NMS. It's constantly updated and bug-fixed, and all of the new content is added as an update, rather than as a purchasable DLC. That alone should earn them some major kudos. This game is worth the asking price, if only for the replayability and active support. NMS records everything I discover, and relays that information in an instant. That alone is impressive, considering everything there is to see. I am always in awe entering a new system and exploring new places. The scenery is incredible. Some places actually feel hostile and dangerous, impossible to live in for any period of time. Others are peaceful and lively, and I find myself spending more time exploring than being productive (I regret none of it). I like to get lost while spelunking or diving, even just flying around. I've got a base in a deep ocean cavern inside a huge crater, and another on a tropical paradise surrounded by flora and fauna. The soundtrack is beautiful. The ambience makes things feel alive (or not). I discovered an "Empty" planet, and it felt so lonely and quiet that it was frightening. I got accosted by a sea monster, and the sound it made after it quietly snuck up behind me almost made me mess myself. I heard a loud cry in the distance, and when I followed it I found a heard of grazing critters. If all you want to do is freely explore at your leisure, Hello Games has given us Creative Mode, which makes everything free and removes the story elements. Absolutely free-roam. This is top-tier simulation, at it's finest. I didn't spend $60 on NMS, but if I had I would still feel like a kid in a toy store. Worth every penny, and then some. Extremely satisfied.
