No Man's Sky

Awesome. Don't wait too long or feel intimidated. Despite the name, you can play them entirely solo, and they're great introductions to the mechanics of the game. You don't need to "get used to" the game beforehand; just jump right into one!

Also, there's only two weeks left, and it might take you the full two weeks to get through it, since you're new. Worth it, though! Also, feel free to contact me if you need help.
