Back in the PS2/Xbox/Gamecube days there was a Godfather game where you played as a random henchman, and it inserted you in all the iconic scenes from the movie, doing missions for the Corleones and so forth. I'd love a game revolving around the October Revolution where you're just some random Bolshevik functionary, taking missions from Lenin, Sverdlov, Trotsky, Stalin, and so on. Maybe you even get to be in the basement when the royal family gets shot. That would be cool. And the gameplay could have a similar feel to RDR2 with the horses, guns, trains, and so on.
