On the one hand, I like several of your suggested games, and I hope they add them. On the other hand, I don't think this qualifies as a game pack, not in a universe where Get Together already exists. I would rather they add some of these within packs with different themes. Or maybe they could have a Game Night stuff pack that adds a couple of these along with a Game Night social event that's cross-pack compatible with other packs that introduce games, and a Party minor skill that helps your sim boost their own and other sim's fun.
