We had those get-togethers often for a period of about a year around the turn of the century. In some cases it was Catan playing, in others we had Dungeons and Dragons campaigns running with the new (at the time) 3rd edition rules. Some days when the whole group didn't get together, a few of us hung out and played guitar, exercised at the local sports center (step aerobics and yoga), or played Spades. We ordered from the local Chinese restaurant often enough that one time when I asked if they needed my phone number, they replied, "Don't worry. We know who you are."
There was much in the picture that was far from ideal, and I was unaware of other problems that would be made clear to me later, but that time still plays as one of the highlights of my life--cherished forever.
