I have been to the Calgary D&D Meetup Group maybe ten times. I always had a good time even though most of the participants are interested in 3rd edition. I played and ran some 4th edition games and always found everyone to be very polite.
I have tried a couple of times to start an old school game at the meetups but to to start a game you must:
1. Consult with the Organizer who retains the right to approve or deny any requests;
2. Post the game on the message board to try to drum up interest; and
3. Receive feedback of interest from enough people to fill the table.
My experience has been that the Organizer is more than happy to have someone propose an old school game. However, I have never received the required interest to get a game started. Which led me to try Red Box Calgary. However, I still have a desire to try to get an old school game at the meetup. I would love to try to expose that group to the benefits of old school play.
So I have decided to try some undercover recruiting. If you are in the Calgary area and would be interested in playing in an old school game (B/X, OD&D, 1E - likely by way of LL and the AEC, etc) at the Calgary D&D Meetups, please get in touch with me - either in the comments below or through my email address on the side.
If I can get enough interest outside the meetup group, we will then have everyone join the group. I will then propose a new old school game to the organizer when I know I have enough interest "in the bag" so to speak.
