I’m in Auckland not Wellington, but the same “OOC commitments” limitation applies to me at the moment.
For me it’s not only things like genre and duration that are limitations, but also location and timing. I want something close to me to limit travel time, and not running late.
Many people in their twenties enjoy staying up late and it doesn’t impinge on any other responsibilities or exhaust you. But as you get older for some people your circadian rhythms change and earlier nights are the order of the day, especially if you have kids to put to bed who might wake up early, early starts for work, etc. Even when we have games that run for just an evening, it’s not unusual for them to start at 7pm and run to 11pm or midnight. I suspect that for the same people that weekend games aren’t so suitable, late nights often might not be either. Especially when you include debrief/aftergame, travel time to get home, and getting out of costume and makeup.
Which is a long way of saying, it might be worth discussing what optimum days and times are too.
For example, for me a good time might be after work from 6pm to 9pm. Or on a weekend afternoon sometime between 1pm to 5pm, or a weekend evening from 6pm to 9pm. It’s not a big deal for me to grab a quick early dinner before a game, that’s better for me than starting at 7pm to accommodate normal dinner time first, and then running late. Others would doubtless differ, so find timing that would suit the kind of people who want to attend, don’t just follow the “usual” larp timing.
