Here's a follow up to my streak of posts that bring into focus some planetary insights gained from the gaming world.
I noticed that the physique of the protagonist Marcus Phoenix is burly and juggernaut-thick. This is true also for the other characters of Gears of War. The sizes of their thighs is as big as a huge log.
Now why is this so? Allow me to propose my own hypothesis. The planet they're standing on must be slightly more massive than earth. The 26-hour day of Planet Sera is a clue. And we all know that bigger and more massive planets have more gravity, which means more weight bearing down on its inhabitants. And being heavier means you need stronger bones and powerful muscles to support your weight and stand upright. Thus, you need bigger limbs on Planet Sera. This could probably explain why their nemesis, the Locust hordes (presumed to be the natives on that planet), come with burly thighs and thick arms, too.
Of course I want to highlight the fact that a creature's physique is directly influenced by its home planet’s gravity, among other things. In contrast, an exoplanet that has a lesser surface gravity than ...
