Canary Beck has a very interesting survey of over 3000 Second Life users (one the biggest data samples I've ever seen), asking them to describe their main activities in SL, and whether they recommend Second Life to others. Respondents could choose three categories, and by far, the largest preferences were Roleplayers, Socializers, and Explorers. These are very familiar and core types of activities in most other MMOs, while other top preferences like Decorator, Fashionista, Creator, and Photographer are very much consonant with activities in sandbox-type games like The Sims franchise and Minecraft.
Just as notably, "Educator" was among the very least designated categories. Taken together, this should finally put to bed a long-running controversy among the SL user community and Linden Lab itself: "Is Second Life a game?" As I've argued before, most people who use Second Life use it for game-like activities or explicitly play it as a game, and this survey data seems consistent with that.
So why do so many SLers insist Second Life isn't a game? More key, why does Linden Lab keep insisting that, even saying so on national television? Canary's survey provides a strong hint of that too:
