@Zoey White Profile seems fine to me, other than Earth not being totally ruined and abandoned. It's just a really shitty place to live.
There are StarDrives that allow travel at lighspeed, so it'll still take some time to get from planet to planet, especially in the outer system.
Gauss rounds, lasers, plasma, shields, it's all on the table. This sci-fi is a bit softer.
