A lot of #esports #casting/commentary is patterned after live sports commentary, but there are two big things that esports often have that IRL sports don't have:-
When I've done casts (most recently #ForgedAllianceForever) I've used both of these a little, but I wonder if there's a space or audience for esports casts in the style of documentary, a blow-by-blow account of a battle from the POV of an in-universe news reporter or military historian, editing together staged camera angles of the significant events to support that format, instead of giving an as-live commentary where invariably a lot of the action takes place off-screen.
