Duke Nukem’s developer, 3D Realms (who started his life as Apogee, then created the 3D Realms brand to stream 3D games) held the Realms Deep 2021 event with a broadcast lasting about 12 hours.
In fact, the important part was the first four hours of the event because there was a trailer bombardment. 3D Realms showed over 80 game trailers in this episode.
Neon Beasts, Beyond Mankind, Prodeus, KULT, Selaco, Cultic, PowerSlave Exhumed. Some of these trailers have not been uploaded to YouTube separately, but it’s not a smart thing to list 80 separate videos in one story. So below you can find a video of the whole event 🙂
The first half hour of the broadcast is already a countdown, followed by trailers and comments from developers. For example, 3:51:00; The trailers end around 4:50.
