While it seems that X4: Timelines is a controversial DLC for many, it offers a much welcomed break from the sandbox by offering a couple of handcrafted missions, ranging from a minute to about fifteen minutes each.
The mission variety very well reflects sandbox activities and range from racing, fighter-style dogfights, carier based large scale operations, simple mining operations, spacesuit handling and even an Assasins Creed like assasination, in space.
Playing those missions reflect some history of previous games, a welcome surprise for veterans of the franchises and something to explore for newbies.
Completing the missions unlocks additional content in your sandbox.

It is important to know that while some missions are quite difficult and hard to achieve the highest ratings, it is by no means neccessary for those sandbox unlocks, where its only requirement is to just play through those missions and achieve the lowest star rating, just a little bit above failing a mission. Therefore, even if you don't want to stress yourself, you won't miss something in the end.
