So I discovered this neat program that isn't really a game but it could very well be someday! It's called Space Engine and it's a universe simulator. You could zoom in as close to a planets mountain range to as far as the visible universe and it'll procedurally generate countless star system and planets, all of which you can explore. There are very warm planets, very cold planets and even planets with life on them. This is one of them;
This is a planet somewhere on the rim of the M81 spiral galaxy. Not only is it a comfort terra orbiting a gas giant, it's a comfort terra with life on it.
One side of the planet experiences the usual light/dark of the day while the side facing the gas giant never gets truly dark. This is how the inhabitants learned that their moon was round as on occasion, they would see their moons shadow transit over the giants face.
A long time ago, people on the giants side of the planet developed very different superstitions to those on the other side, which caused many wars. Now, the planet is entering an industrial age with the giant side being the more technologically advanced. But one of the traditions that holds over from the past is the season where the gas giant obscures the light in the middle of the day
The M81 spiral galaxy is clearly visible and on other parts of the planet, neighboring galaxies are fully visible, spawning slightly differing myths in relation to the presence and absence of the gas giant. This time where the giant obscures the sun is the best time for the moons astronomers to observe the night sky as it is the darkest time of this side and the giant normally brightens the night sky to where you can't really see many stars.
