Ppreviously played Cluedo and Exploding Kitten very casually maybe 2-5 times a year.
Then 3 years ago, I joined a Talisman (4e + Dungeon expansion) 6 player game that lasted 5.5hrs and I stayed in the chair from start to finish. Won the game by 1 turn after completing the dungeon and teleporting to the crown which was being used to finish me off by the last player.
There was assistance from other players with rule clarifications and some tips, so not a solo win.
Now 180 games in the collection(with 30-40 Wall o Shame), I’m regularly exploring the mechanics and previous classics that are out there.
