This is hard because I can't play without Seasons. When I first bought the bg and started playing, immediately, the number one thing I felt was sorely lacking was changing seasons. IMO, the bg should have at least included that, if not the calendar and everything else. But that EP doesn't come with a world, so it's a big tradeoff. Anyway, I guess I'd keep Seasons regardless, plus Parenthood (the second pack I bought) and Kids Room Stuff, otherwise playing kids and teens would be too boring. The only kits I have are the two free ones; I'd keep Fashion Street since at that point I'd want the little bit more cas more than I'd want another bar or couch (i.e., from Desert Luxe).
From this, it looks like I value gameplay over building, but I do like building, too. I'd be sad to give up SE, CL, DHD, SD and a few other packs that I especially love for the bb.
