I am min-maxing also. But it really depends on what number I am min-maxing. The ordinary powergames are too much fixed just on damage numbers itselves. I enjoy min-maxing number of minutes to finish the game (speed runs), the number of kills (pacifist, murder-hobo), the wealth (bare-hands, empty inventory), number or reloads (no-reloads, iron-mans), number of finished quests (completionist, and also any% speed runs) and many more. Funny note: my latest tabletop DnD character has min-maxed backstory. I re-flavored and nerfed his spells and abilities to best match the given narrative. It was very fun to create that build and it was very rewarding to play him due to constant need to be creative.
