Game guide: Easy friends
The Sims 3
Normal gameplay
If you need fast friends, there are heaps of ways to get them. One of the ways you can use is buying the Office Hero lifetime reward and building up Charisma skill. Then, you will become friends with your co-workers very quickly, if you pick the socialization tone. This varies from career to career. Examples are "Chat at water cooler," "Discuss News with Co-Workers," etc. An easy way to get friends, with no effort on your part.
But the next way might be one of your favourites. Buy the Legendary Host lifetime reward, and meet some Sims. Then throw a party, inviting them. With Legendary Host, they will always come to the party, even if they hate you. Just invite the same Sims for a few consecutive parties, and watch the relationship values soar. Even if you mistreat them, they will still get a gain.
Playing a Guitar in public with a high skill will increase your relationship with anyone who watches, also an easy way to earn money.
Three easy ways to get friends, which are guaranteed not to mess up your game.
