Yes I do, (but)...
I don't have to connect all the series or have it make sense. I do when it suits me. I love the game giving me a backstory to work with though.
I've recreated a whole Sims 1 and 2 save to include as many details as I can from the series I loved .. since I didn't play 3 mostly anything that happened there I've left out .. unless it suited the story for me. Like Bob Newbie in my current Sims 4 save is a bookworm. I learned that Sims 3 did that and it helped round him out in my current game. I happily ignore things that don't suit how I feel about a character though.
They have given us a few stories here in Sims 4... like Johnny Zest's and the Villareal household have some mystery we can work with ourselves. I hope they give us more as time goes on but kind of doubt they will. I wouldn't mind all new stories especially.
I can understand though at some point these stories might not make sense or might even offend some folks (go figure) since they've gone in different directions with different iterations and some just won't make sense to timeline them together at this point.
