The standard line games you mentioned are fun, though it requires quick wit, which some people don't enjoy playing (I used to rock 185 but my improv brain crushed that skill into oblivion and now I'm totally useless at it)
You could do press conference, where one person is delivering a press conference/prepared statement and the rest of the players are reporters asking questions, with their lack of comprehension and assumptions being heightened as the game goes on.
Similarly, you could do Expert Objection, where one person is moderating a "debate" on a certain topic, the goal being to be the person talking (holding the floor) when the game ends. They can object on content accuracy, delivery skills (posture, voice, confidence), and just devolve into nit-picking bullshit. One person is in charge, sort of moderating, asking "on what grounds" when someone says "I object" to interrupt and try to get the floor.
Slow motion samurai is fun, but I cant see that being really fun for the players more than 2 or 3 weeks in a row.
You work your life away and what do they give?
You're only killing yourself to live
