Picked up No Man's Sky last week and I gotta say, for all the (probably warranted) flak that the developers got for the state of the game when it first launched..I'm absolutely obsessed with this iteration. You get to fly around space, identify minerals/flora/fauna on any damn planet you can see, mine various components, sell goods/artifacts, build up a sweet home base, and play mechanic when fixing up broken down ships you can find abandoned on planets. This is the exact kind of chilled out low-stress game I've always wanted to have to counterbalance playing CSGO/Rocket League that need your constant attention.
I don't know if it's still 50% off on Steam, but for anyone who likes space exploration that you can do at your own pace and rarely have to worry about dying (I'd imagine depending on difficulty - I selected less hardcore), check it out.
