When I went through the "Motivations" section, it immediately struck me that they had no items addressing one of the things that I like most about playing D&D, which is discovering new aspects (people, places, things) of the fictional world. This piqued my interest enough to do a quick inventory of their items vs. the long-known, but widely ignored eight-part taxonomy of fun in games. *
Long story short, WoTC's survey items completely miss 2 of the 8 categories ("Discovery" and "Submission") and a third ("Narrative") is either absent or weakly addressed depending on exactly how you evaluate things. Seems like whoever put the survey together did not do their homework. Or perhaps the exclusion was more deliberate, though I have a hard time imagining what the reason for that would have been.
OTOH, WoTC's survey items did cover some things not included in the eight categories. First, they include some queries directed at what one might term "Community", that is, the interest/benefits of interacting with other D&D players
outside game sessions. Since the original taxonomy emerged from consideration about game design, it's reasonable that they wouldn't cover that; it's reasonable as well, of course, that WoTC
would ask about that.
More interestingly, a couple of WoTC's survey items broach a concept that isn't really covered by any of the 8 categories, but perhaps should have been - group leadership. The closest the 8 categories get is "Fellowship", but that is usually described as focused on desire to be part of a cooperative group; motivation based on being the group's leader is a bit different dynamic.
* Not the original source, but the most fleshed-out description that I know of is here:
Gaming for Fun (Part 1): Eight Kinds of Fun. Also, no such taxonomy is going to be beyond criticism, but it's always seemed to me to be a decent attempt.
