Hands down the Most Varied Space Game out there. It won't make you grind as hard as other survival games but will still leave you feeling accomplished. Creativity is through the roof! I'm 60hrs in and still find new things in each new star system.
You can follow any one of several plot lines simultaneously. You will never run out of things to do and your Mission Log will always have good suggestions. You really do go at your own pace here which I love. Sometimes I change settings just to relax while playing, but combat is varied enough to stay entertaining too.
New civilian settlements update adds another excellent layer of completion to it all.
