Sincere thanks to everyone who showed up. I hope everyone had as much fun as I did. Despite Legions' shortcomings that we all know about, it definitely has something special that makes it worth dusting off every once in a while.
I would encourage you to plan it. I am an admin of the Steam group now so I can help you put an announcement on there. I would caution you that at least half of the people at the last one shared the sentiment that they either never want to play again or not for a while. That being said, between the half that did enjoy it and those who missed it, you should be able to get at least a dozen people. The trick is reaching out, not many people check this forum, and several don't have Steam or don't pay attention to the Legions group.
