If you're getting bored with the game, then this is the way to go.
You can download just about anything for your game, whether it being a skin, wall, floor, house, or object. (If you're having problems installing the game or any of its expansions, see the troubleshooting section of this guide.) - DOWNLOADING FROM THE NET - This aspect of the game is by far the best. It'll save you the pain of having to reinstall them all every time you buy an older expansion first. If you plan to get them all eventually anyway, it's better to buy them in order than to pick favorites.
The Sims, The Sims: LL, The Sims: HP, The Sims: VC, The Sims: UL, and lastly The Sims: MM.
So then you would install them in this order. If you decided to buy the House Party expansion pack later, then you would have to uninstall ALL the games and reinstall them in order so that they run properly. Afterwards since Makin' Magic is the last expansion to come out, you need to install it LAST. If you were to install it out of order, than some of the interactions and objects from a later expansion might cause your game to have severe problems.
Why? Living Large was the first expansion in the series to come out. Then you need to install living large next. Since you already have the original game installed (if not, reinstall it FIRST). Here's an example of what to do if you bought living large, and Makin' Magic only. This adds many new interactions, and fun situations to The Sims game. The Sims: Makin' Magic - Why watch Harry Potter when you can join in on the fun? With this expansion it's all about becoming the neighborhood witch or wizard. Then go home and practice your lines for being a sitcom actor on the side. Go to the new studio town and build up your status by taking up singing, or telling jokes in a comedy club. The Sims: Superstar - You can be come a famous superstar! This expansion lets you actually have a "job" that you can go and work at. There's also a completely new neighborhood/downtown setup to your neighborhoods.
Pets! Also adds some new interactions and objects to the game, like working a garden. You can visit an assortment of different types of places (mountains, camps, beaches, etc.) The Sims: Unleashed - Adds a surprising new addition to the game. The Sims: Hot Date - Adds and entirely new section to The Sims.Downtown! Why stay at home when you can go out? The Sims: Vacation (On Holiday) - Want to get away from work? Then just go on vacation, this one mostly brings objects and interactions for going on a vacation. The Sims: House Party - Adds mostly objects and skins with some new interactions to host a party theme at your Sims home. The Sims: Living Large (Living it Up) - Adds new functions, objects, interactions with The Sims, more jobs and plenty of new action to the game. The Sims - I think we all know what this ones about. Now it's alright to buy whichever you want, just make sure you install them in the order that they came out. YES NOmanual about it for more information). If not, installing them out of order may cause damage to your game (check the The newest being Makin' Magic Since you HAVE to have the original Sims game for the EPs to function, you also really need to buy them IN ORDER if you're going to get the expansions.

EPs (EXPANSION PACKS) - As you may or may not know, you can buy what's called an "expansion pack" for the original Sims game that allows you to add more exciting features like, pets (unleashed), downtown lots (hot date), and have parties like it's 1999 (house party). So hopefully this new guide will help you through some of that process. INTRO - The one thing people have trouble with The Sims most, is installing items, EPs, etc.
