https://dropbox.com/s/96g9r1ejqvwr3ho/Sims%201%20not%20in%20Sims%204.png?dl=0Link to picture of Sims 1 objects that are not in Sims 4 - most from EPs. However, as you will notice, many of these objects did not make a return in any subsequent Sims games: the underwater diving tank (though Sims 3 diving skill outmatched it), the bookcase from Makin Magic with a secret compartment for spell components, the indoor sky diving object, the cake the dancers came out of, the harvestable beehive, the wine cellar (Sims 3 did have an equivalent however in World Adventures but it didn't store actual wine to my recollection), the wine press (it was really more fun watching Sims stomp on the grapes in the press than watching them use the World Adventures nectary), and the canning station (though a modder has made one now for Sims 4). The baker's oven technically wasn't in any other Sims game, but the Sims 3 store offers a baker's oven. The butter churn also hasn't been in any other Sims games.
Pantries also haven't been in any other Sims game, and satellite dishes that work to bring in more channels also haven't been in any other Sims game.
Not shown in this picture from Sims 1 that hasn't made it to Sims 4 yet: Makin Magic beanstalk, Makin Magic vendor stalls, Snake Charmer, Makin Magic mini golf, Makin Magic placeable coaster tracks, Superstar spa steam machines, Unleashed produce market stall, Unleashed New Orleans build mode items, Vacation beach volleyball, Vacation toy boat rentals and feedable ducks, Vacation arcade games, landline phones. Sims 1 never did have official driveable cars or motorcycles, but I believe Simslice made hacked motorcycles that were drivable by Sims within the residential lot they were on.
