Now I might be overthinking the concept of bluffing as a game mechanism, but that's just what bluffing wants me to do, right?
Which leads us to Odd Hackwelder's 8 The Liar from Swan Panasia and his Hacko Games. While this game has more components than a microgame — 72 cards(!) along with some chips and player cards — the game itself plays out like a microgame, with everyone bluffing and bluffing again (or not) while trying to shed cards and chips.
