I’ll recommend David Wong’s Zoey Ashe books, similar to Scalzi in style, and I would say similar to Snow Crash in world build, but way less formal. Futuristic Violence and Fancy Suits was terrific. Zoey Punches the Future in the Dick less so but still grand. And now I see a third one that escaped my attention and I’ll have to get on my phone for this week’s travels.
His John Dies at the End series is also incredible, but not quite the scifi you’re looking for. More Buffy/Supernatural style, well, in a Trey Parker/Matt Stone vein of Buffy, lots of dildo jokes.
And though it’s not scifi I’ll recommend the Gentleman Bastards series by Scott Lynch. Oceans 11 conmen caper in a LOTR world with dialogue by Quentin Tarantino. I recommend it to everyone, whenever I am given an opportunity.
I’ve been doing LitRPG (the realityTV of fantasy) for a while now, if you’re into it: Just started Battle Mage Farmer, less stats and more proper fantasy story, not as meta. But engaging, and a unique way to cap MC overpowering. He Who Fights With Monsters, on the sillier side but it has a lot of heart and 80s movie references Primal Hunter, about at textbook LitRPG as it comes, but I like most of the characters, I guess. Slow build, I think it’s on book 10 and nowhere near Max level. Fifth Era Apocalypse. Most likely to stem directly from a DnD campaign rather than SNES JRPG. System Universe. Most OP protagonist, it has a very popcorny Fast and Furious just go with it style. Mayor of Noobtown, I think it was my first, and still lots of fun. Kingmaker. My most recent, not as good as the rest but it’s still early. Has time to find it’s way. Nope. Ascend Online, more mmoLitRPG, and also reminds me that I dabbled in more haremy LitRPG stuff before, mostly stuff by Harmon Cooper. Kinda feel dirty about those.
