Here is my own personal marathon timeline I try to go through every year, especially before major releases. The titles of each chapter were taken or inspired by
TheBatMans chronology and how he divided the games. Titles with red letters symbolize main events, have gameplay, and feature main characters. While the words with black letters only are CGI and game movies from my own library or pulled from Youtube.
I don't include the retelling of main events from the Chronicles games because I feel it will become too redundant and repetitive, disrupting the natural flow of a marathon.
I combined some of the scenarios from the Chronicles games, such as Umbrella's End. It's comprised of Wesker's Report I, Umbrella's End, and Dark Legacy all in one. Survivors is the last cutscene of Memories of a Lost City and The 4th Survivor from the Chronicles games since I feel that provides the most story context of any iteration of Hunk’s scenario.
I know that its missing the manga's but after reading them once I feel like not reading them again, not a fan of rereading things. If anyone is curious about them;
Prelude to the Fall would be between Dead Aim and Umbrella's End,
The Marhawa Desire between Rev2 and RE6, and
Heavenly Island after Vendetta.
Edit:
Extra's are old or grey/non-canon material that is not necessary to the overall plot, but can add extra depth to the experience. Removed Redux title and RE1.5.
