Love! For James Cameron and Aliens. And the great utilitarian design of the spaceship interiors. Great world-building.
Cryosleep? Ice sublimation and mummified Sigourney Weaver. Hibernation. How to shove pine cones up your butt, chug some Nyquil, and turn into a bear. Cryogenic specimen preservations: sperm! DIY fecal plugs for hibernation.
The rise of private space industry. Going dystopian.
Planet? Moon? The delineation between planets and moons and looking forward to the future when we get confused again. Demoting Pluto to planetoid. Terraforming Mars. Sad news on Martian CO2 supplies for atmosphere creation. Crater settlements and whether or not you need a roof. Atmospheric density limits for human comfort and thriving.
But are they really called Xenomorphs? The throwaway line in Aliens that spawned decades of confusion.
Send the robots
Always send the robots. Unless you are an evil corporation with shady goals. Milk robots…?
Blade Runner and Aliens are the same universe. The separate lines of technological development that yielded replicants and Aliens’ “synthetics.” Blade Runner 2049’s anime prequel and how that informs the universe crossover.
