Foundations: A LitRPG Adventure(Tower of Somnus Book 1)- Didn't like it despite it being based around an interesting idea. Fantasy with aliens good. Game giving real world powers bad. Cyberpunk story good. The big bad being a jealousy teen girl used by her mother bad.
Drone Ensign- Scifi litrpg based around the idea of humanity as an insect colony complete with drones, soldiers, etc. Not bad so far.
I also picked up AMOK by Barry Eisler though I haven't started it yet. Eisler writes good action/adventure sat in our world and this story is about Dox, one of the side characters, from his main assassin series.
Are you okay with picking up a story that's still new? You might want to check out A Summoner Awakens by LC Taylor. It's a regression tower-climber with deck building. There are only 10 chapters out at the moment, but it's off to a strong start.
A more established option would be Tower of Somnus by Cale Plalmann. This one's cyberpunky with aliens, and has three books out on KU.
Finally, there's Infinite Competitive Dungeon Society by Toika. I believe it was one of his first novels, and if you've read any of his others and liked them, then you'll probably like this one too.
It should be on KU, KIndle, and Audible.
I don't use KU so I can't link that, but here's a link to the amazon page of thiis book.
