WBC (World Boardgaming Championships) in Seven Springs, PA has an A&A Revised Tournament (with modified victory conditions to fit a Over-The-Board Tournament) yearly as part of its con. Not 100% sure of the date for next year (it’s a two-day event at a week-long convention), but judging by the first few years A&A is on the first two days. This year the tournament was on July 22-23.
boardgamers (dot) org is the website iirc, but you can also just search “Boardgame Players Association (BPA)” and it should come up in the first result or two.
We had about 20-ish people show up this year with next-to-zero promotion/hype, which was a pretty good number considering how niche Revised is compared to G40.
Side-Note: Larry Harris and crew were at the convention to demo War Room this year, so if you’re looking forward to that expect a push for it to be an event at future WBCs.
