waitwaitwait, they're okay with K-ON!'s stuff, which is a group of 16-17 year-olds in-universe, but can't get past the in-universe ages of the iDOLM@STER cast?
wut.
I actually don't really get people into it, though there seems to be a slight interest it in other places I go to because of the anime. Since it shows up a lot in fanart and the like, people see it as "oh, that thing is getting an anime, wonder what it's about." Maybe I'll make my boyfriend watch the show so he can actually get it :V (he still thinks its some dating sim like thing derp).
It's more about iM@S not being known rather than being okay about the age: he had never even seen how the idols look like at the moment I had him listen to THE iDOLM@STER for the first time, let alone what iM@S is. The collective voice of the 9 idols does sound less like adults and more like below average teens.
Also, the presentation of iM@S itself does look a helluva lot like dating sims. Without putting a little effort into knowing about what iM@S is, people can easily mistake iM@S for a dating sim
I've always asked myself a question: "How do I explain to people what iM@S is?". I still can't get a quick and just answer :shrug:
