from my experience, spyfall is much better enjoyed with a group of friends in a setting where you can just hammer out 5 games or so in quick succession. unlike resistance/werewolf, you really don't want to get too attached to any individual game. the experience of asking dumb questions and having them become a meme in the next game (and silly stuff like that) is much better than any real gameplay "tricks" there imho
it's an underwater adventure ride
