I'm a big fan of the Borderlands series (Well, 2 and on, 1 was kinda meh), and as I understand it, the developers had astrophysics consultants to make the world work right. However, in the only interview I've found about the research, Anthony Burch (the head writer) gave an inaccurate description of the planet in-game. So here's what I have gathered about the nature of Pandora from in-game information and observation:
1) It has a highly eccentric orbit, giving it planet-wide seasons. Planetary summer lasts 3 Earth years, planetary winter 7.
2) During perihelion summer, it is tidally locked to its star. We can tell this because the star is not in the sky during gameplay (more on that later). It may or may not be tidally locked during its aphelion winter, no evidence one way or the other so far.
3) Either way, the day side of the planet is almost the same each orbit, but may shift slightly over time.
4) The habitable zone does shift slightly over time, as one area that was a major shipping port is under deep freeze in this cycle (suggesting a trailing edge to the habitable zone), while another area that was tropical, wet, and had seas is a desert this cycle (suggesting a leading edge)
5) As noted, liquid water and a breathable atmosphere exist on this planet. However, the state of the water, and which areas are wet and dry zones, is not stable.
6) Gravity is slightly less. Not enough to cause atrophy on long-term residents, but enough so that a normal human who gets intense regular exercise can run faster and jump farther than they could on earth.
7) The planet has one moon, which is unusually large and/or close to the planet compared to our moon. The moon rotates and goes through phases rapidly. It is hard to get an accurate measure of the period (due to the fact that the game's time scale is off), but the rotation and phase shift are not in synch.
8) The habitable zone is relatively small due to these extreme conditions. The area the game takes place in is on the "night" side of the planet during perihelion, where it receives reflected light from the moon. The moon's phases act as a day/night cycle for the habitable zone, and presumably the amount of reflected light is one of the contributing factors to a region's climate.
9) Life exists on this planet, but in an extreme state befitting its extreme environment. Species are able to go dormant for very long periods of time (either by hibernation or dormant eggs). There are multiple successor species for when a different environment exists in a region, and any woody plants are invasive species.
That's all I got for now. If you need any more information, I can try to find it. It strikes me as plausible, if highly unlikely, but I don't know very much about the subject so I'd like some help if you can.
