CLUSTER GAME-CLASSIC-ENGINE · 34 ENTRIES · EARLIEST ENTRY 2018-04-15
Classic game engine reimplementations
This cluster consists of open-source game engine reimplementations and source ports that let players run classic titles (e.g., Morrowind, Doom, Diablo) on modern systems using original game data. Entries appear in most months from April 2018 through May 2026, with occasional months having no new members and a few months having two. Traction is led by Homeworld-RTX with 1 star, while DXX-Rebirth and Doom BFA each have 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
