Mercury is marked as tidal locked in game, except it's not tidal locked it has a 3:2 spin–orbit resonance which is different. This is especially important because of the maximum population. Since with tidal locking we assume that there is a zone in between the two halves of a tidal locked planet where it is (more) habitable, reducing population and the temperature part of colony cost. For mercury this is not the case. It shouldn't be labeled as such. This has been brought up before and Steve is aware of it and marked it that way on purpose, however this got me thinking.
It seems that in aurora basically all planets close to the star are tidal locked, while in the solar system none of them are, which is weird. Doesn't that mean that based on what we can tell from the only real life examples we have that it is much rarer for a planet to be tidal locked than aurora suggests? For example there are no extrasolar examples of 3:2 spin–orbit resonance, might be something that could be added.
