Oldest member is 43 this year, youngest member is 22 this year. Largest chunk of the group was born in 1987, so turning 31 this year. I lean towards the older end (but am not the 43-year-old).
I was pretty amazed when I told my dad about the game and he wanted to play. Youngest to oldest... I think almost 40 years. So yeah, I'd call it an age gap. xD
54 to 15 in my main group. I am the 54, the 15 is the child of a couple who play with us - and very much enjoys the chance to be treated as an adult by her parents.
