Kerbal Space Program is a space simulator. Taking place on the world known as Kerbin, a group of creatures/people/"intelligent" organisms known as Kerbals (all of them in the Kerman family) have built a space center suitable with parts suitable for creating complex spaceships, space stations, aircraft and the like (more to come like planetary bases, rovers etc.) It is up to you to help the Kerbals put all of these pieces together to create amazing transports to explore not only Kerbin, but it's moon called "Mun", it's second moon "Minimus" as well as many other planets orbiting its sun and some of the moons orbiting those planets.
https://kerbalspaceprogram.comYou may or may not be a space simulator fan, but this game is really intriguing to me, it's very complex with all of the realistic features if offers from real physics to orbit mapping, in space docking etc. This game has not been fully released but you can buy it (as I have) or simply try it out with the free version they offer. The free version does not have all of the features as does the paid version but it gives a good feel of what the game is about and what it's like. For me this game has been very challenging but has been very fun to play.

Launching My Minimus Mission from Kerbin. (Kerbin is the planet instead of earth, minimus is the second moon other than "mun", which is like Earth's moon.
Having obtained a stable orbit around Kerbin, preparing to altar my course to intersect with the path of Minimus.
Both Kerbals from the start of the mission after having landed on Minimus, one using the single passenger lander, and the other using only his jetpack.
Another mission with my Mun Station maintaining a stable orbit around the Mun.
An in cockpit view of the same stable orbit.
The Mun Lander that was brought to the Mun in the same mission as the Mun Station, accelerating against the force of gravity of the Mun attempting to land.
