This system is flawed. You also stated more than 3% of new accounts were seen as being 13-17. So what do you think adding this safe wall will do? These kids will put an older age to see what’s going on, so now this “more than 3%” rating will inflate. I know the comment to respond will be like “well then that is up to the parents.” You don’t think that you are also responsible for it by wanting to keep your target audience open?
Which I will get into now. You state that another worry and need for this age change is this:
“Mature app-store age ratings are also increasingly limiting app availability, discoverability and access to featuring opportunities on the app stores. That makes it harder for the adults we actually want to reach to discover PIMD. To keep campus lively for years to come, PIMD needs to continue welcoming new adult players into the community.”
If these people you’re “trying to reach” don’t have adult games popping up onto their suggested games and rather younger rated games popping up are you sure those are types of people you do want on your game? Doesn’t that make you question why adults you’re trying to find to make your game community and revenue larger have kid centered games pop up rather than something adult targeted?
