Scenarios have come to The Sims 4, and while goaled play is not my usual thing I am glad to see more options for those who enjoy specialized challenges, and I may come across one I do feel like giving a try at some point, myself.

But they seem to generate a lot of specific discussion relevant to their particular aims. Just like with Packs, people like to do the new thing, and talk about it (or ask questions, seek advice, etc.) here.

Perhaps Scenarios might benefit from dedicated space on the Sims 4 Discussion Forums? I have no idea how easy or difficult it is to set up a category, from the back end, but if it's not a huge undertaking, you might consider it.
