Something that has come up more than once with the latest quest is that it feels uninspiring (at least, according to the individuals I've spoken to).
I think it's worth discussing a bit what we're looking for, since the complaints I've gotten about it were along the lines of, "It's just not interesting. Who wants a random table of nonsense?" That isn't what I got from the quest at all, but I can see it, since the description explicitly throws out some staples of Ye Olde Style Gaming as examples.
In my mind, the quest is much more about an old school vibe, feel, and style. We're less concerned with conforming to old-school mechanics as we are about recapturing some of the elements that made it fun. When I think of old school gaming, I think of the adventures that didn't take themselves too seriously, that weren't concerned with always being moody and thrilling, but instead could include a ridiculous situation, that could make a joke and be funny. Sure, random tables were a part of a lot of adventures (just look at the 1st edition DMG), but those were intended to help guide the adventure and provide content when a GM couldn't come up with anything else, not be the end-all solution to generating encounters.
Can we get some other thoughts about what old school means, so that we have a better baseline for people to be inspired from? As-is, I'm not sure the description provides enough to go off of; it suffers from the lack of specificity generalities often do.
