I realize the list is not complete, but not knowing what's planned to be added, I'll comment on one gap that immediately caught my attention. You may want to consider a few more high-school related options in that starter grouping. My high-school experience (and I'd suspect most other people's) included more than just jocks.
Yes, a few of the other starter options might be attending high school as well, but there's no room left for say, the middle- or lower-class kid who didn't live on the streets, isn't a hacker, has no relatives in the Navy, isn't a jock, but still attended high-school.
