1. "Line of Dreams" - a trilogy based on Master of Orion. It's clear that he spent a lot of time on this game, wrote from the heart, had a grudge against the Darloks, fought with the Psilons, cooperated with the Bulrathi and the Alkari; the book is essentially based on a playthrough of a specific game.
2. "Knights of the Forty Islands." The author spent his youth in Central Asia and captured the Soviet period, when every street was like an island, and strangers were simply beaten up. He definitely based the characters on real people. I really liked it.
3. "Cold Shores" - a worthy and solid science fiction work, one of the best in the Russian language.
4. The novella "Atomic Dream" might be one of his best. It's captivating.
Perhaps these are his worst works.
1. "No Time for Dragons." Damn, I expected much more from the collaboration with Perumov, but it turned out to be a secondary plot with secondary characters.
2. "Rus' Island," co-authored with Burkin. It's part of the "Let me kick..." series. There's definitely more Burkin in this book than Lukyanenko.
3. The Night Watch series. Not my cup of tea.
Overall, I respect Lukyanenko for his stance against taking Russian children abroad.
