War games.

It’s often said death is a gateway. However for Jack, the gate remains closed. After dying he’s brought back, a thousand years in the future, and tasked with saving his family by any means necessary.  Just a little sci-fi litrpg project I’m on. The tech and high level galaxy is very sci-fi, but the combat is more fantasy.  A content warning here. The universe is a very socially stratified system. There are serfs. Commoners. Nobles etc. if that’s a trigger this might not be the book for you.  The mc isn’t an anime protagonist who goes insane and buys a slave the fist chance he gets. But they do exist in the world at large and that can’t be a no go for some.  There is also a lot of violent combat. Which I know can be a no go for some.
