I would be ok with a gamepack. That being said, I think a lot of the things that people find lacking for children, especially, could be solved by continuing to do with future packs with any theme what they've done with CL and the upcoming base game patch: add functionality for children to participate in the same activities that other ages do. For example, they really need to go back and add animations for children to ride bikes. We shouldn't have to buy a whole new pack for that, as it's something they should have done from the beginning, so they should go back bit by bit and add those things in patches. If they would do that, and continue to add occasional new objects specifically for children (the playtent was nice, a treehouse would be even better) and if they do a better job of including child animations for future objects and activities... particularly if they ever do some sort of hobbies pack... then I think that would already add a lot.
But I'm not opposed to an additional stuff pack or game pack. I also agree with some of the comments above about enhanced group play for kids. I also really want more afterschool club options, but again, we don't necessarily need a kid-specific pack for that; remember, we got drama club with Get Famous. If we do indeed get a singer/bands/music pack, I would sincerely hope they would take the opportunity to add afterschool clubs for band, music club, and/or chorus/glee club/a cappella club. As long as they do a better job of integrating children's activities and group/family content into all themes, which they need to do anyway, then probably that will be enough to make me happy.
