This got me thinking about other ways characters may showcase their skills or put them to the test against other players through an in-character contest of sorts. The dart board exists, but I can think of similar things.
Punch tester machine: an arcade-like machine that has the user punch a bag as hard as possible and rates how powerful the punch is on a numerical scale. Brawling.
Break-boards / wood boards / cinderblocks: An age old flex for martial artists, break manufactured break-boards at Corporate gyms, or scrap wood boards and cinderblocks in Red. Martial Arts.
Tameshigiri stand: Cut through synthfiber tatami mats, more cuts before the mat falls is more skillful. Long blades.
High striker: Another arcade-like machine where the user is instead rated on how well they swing a hammer. Melee.
Why? Sometimes it is interesting to have a way other than sparring to assess people for training scenes, and impromptu or even organized competitions can easily be started around some of these mechanisms.
