Fantasy gets most of web fiction’s flowers, swords, and terrifying word counts. Meanwhile, science fiction is quietly uploading aliens, artificial minds, doomed spaceships, and existential crises with much better lighting. Best of all, these stories actually end.

The Last Science — Etzoli (Royal Road)

The audience is smaller, which means the top-rated stories got there through quality rather than genre momentum. Every seral on this list earned its audience.
