Something that new players don't understand is Master's divisions. There isn't an intermediate or recreational or novice Master's division, so new older players will start in the non-age protected divisions. IMO that's a huge mistake.Well that sucks; Really getting me excited to go play now :|
Basically all of the old guys with skill play MPO, so MA40+, MA50+, MA55+, etc., are pretty low-key divisions. Not much sandbagging, not much of the drama that comes with youth. When I was in my late 30's I was playing INT and hating my life. The first event that I played after I turned 40 only had Pro Masters as a division but I though "why not?" and the vibe was 100% improved. Everybody in the Master's division understands we are not the next McBeth (mostly because we are all older than McBeth anyway) and the competition is a lot more chill.
I would strongly encourage you to start in the Master's field.
