Seasons offer not just new gameplay, but also revamped the graphics on the weather and the seasons just blows you away.
The first thing you will see improvement is the graphics. The sky changes according to season and the weather, and also the increasingly impressive effects of rain and lightning during thunderstorms, snow during the winter and the leaves of the trees change during winter. Just looking at the surroundings change as seasons come and go is very breathtaking.
The seasons are not just added asthetics to the game, it can simply take a toll of the lives of the SIms. Sims can get too hot in the summer or freeze to death in the winter. Spring blossoms romance, Summer enhances friendships, Autumn makes skill building easier and Winter bonds the family. Basically this expansion pack is not sided towards Sims of certain aspirations unlike other expansion packs did.
Tons of activities offered in this expansion, most of them have assiociations of the environment. Growing crops and harvesting them, fishing, snowball fights, snowmen building, play in piles of leaves as well as catching butterflies and fireflies. There are also a lot of objects that keep Sims entertained such as the pool slide for the newly improved swimming pool, skating rink, a juicer for making delicous juices and so on.
What I felt unnecessary is the inclusion of 6 new career tracks in the game, which I think it is fine without them as players are always don't see what are they doing while they work. Thus there is no significance in the game.
All in all I think this is the expansion pack everyone is waiting for. This is definately a must buy for Sims fans!
