I guess it's about time I'm bowing in. I joined quite some time ago, but didn't know there was a welcome thread. I think I became addicted about twelve seconds into my first puzzle.
I'm almost 66 years old, so I don't know if I will fit in well; I assume I'm well above the average age, even though this game seems the type that attracts "the experienced problem-solver." But I'm what my wife calls a big kid. When two grandkids are in the house, she has to deal with three kids.
Originally, I was hooked on interactive fiction (Zork, Myst series, that kind). Just as I was getting over that, FC came along, without giving me time to brace against it. So here goes another 30 years, if I last that long. I'm amazed at the genius behind this type of game. Good job!
