If there's one single expansion to get out of the lot, it's this one. On top of that, the gardening career is a nice bonus and offers Sims the option to work from home as they look after plants all year around. Hot and cold weather outfits are crucial for Sims to cope with heatwaves and sub-zero temperatures, while families and friends can gather to celebrate annual holidays together. The calendar feature is a game-changer for The Sims 4, as the addition of the four seasons (with weather, temperatures, and seasonal events) brings a greater sense of time progression and realism to the experience. Seasons dramatically enhances the core of the game, and we can't imagine playing without it. While all of the other packs are somewhat dependent on whether you're on board with the concept and how it complements your playstyle, this is the only expansion that we consider a must-have for all players.
