I think there can be some new categories.
First is normal Any% in-game time;
Second is Death%, "Die as fast as possible";
"Boss kill%" (Dogman, DMC guard, tribal guard, DMC drone, Merga ghost, Yezinka);
"Tourist%" (visit all plot encounter locations);
"Aquire rare/expensive item%" (DMC armor set, Gauss rifle, gun, Jar of screaming eyes, nanobot kit, cart/sled/travois, DMC bracelet, YpcV, other items);
"Map opening%" (1/3, 2/3 and all map).

Actually, the run in "Merga Wraith" category is made even before making aditional categries to this game.
