How to unlock the Epic Party achievement in The Sims 3 - Definitive Guide
Anyways, start a new game, choose the Landgraab household that is in the south east corner, these sims already have a bunch of friends.
Set up a fundraising party at the Rendezvous Cove (beach that is left to their house), make dressing swimwear.
Simply attend the party, have your sims set to free will, so all you have to do is watch, at the end of the party you will get the achievement.
This worked for me, it should work for some others.
Also, do not change the time, otherwise this will "glitch" you out of the achievement first time.
You can purchase lifetime rewards by pressing X then using RB/LB to select Sim info and scroll across using the left analog button. Enjoy your achievement :)
If you have more than one sim in the house make sure the sim with the legendary host activated uses the phone to throw the party.
I recommend wedding party because it seemed everyone got a big boost from watching the wedding, which helped with the achievement.
I unlocked this achievement today by simply hiring the Moonlight Bay Public Beach for a party.
To hire a venue simply click on your sim, then "cell phone", then "Throw Party At...", this will then bring up the town map for you to choose a location. I chose the beach, but this might work with other locations too.
I then entered the dress code, I chose swimwear for the beach and party start time, I chose 4pm on a Sunday simply because my sim wasn't at work at this time. I invited 8 people, a mix of old and good friends as well as acquaintances.
Due to the venue being hired for the party I had no preparation to do. It cost 250 simoleons to hire and a reminder popped up on the screen to ask if I wanted to go to the party or call it off.
At the party I simply had my sim chat to a few people and I had the time speed set fast. In real time from start to finish the party probably lasted around 2-3minutes and the achievement popped as soon as the last guest left.
This trophy is really easy if you have the lifetime reward legendary host. When you have this lifetime reward you will have an awesome party no matter what. You can buy these rewards by pressing and going over to the sim info tab. From that tab go to the lifetime reward tab and click on lifetime rewards. There you can buy any reward you want. Buy this reward and throw a party.
To throw a party click on your sim and go to his/her cell phone, you will see an option to throw a party. It can be any type of party, it can be anywhere and it can be at anytime as long as you throw a party. Once all the guests are gone your party will be evaluated. If you have the legendary host reward then you will have an awesome party and you'll get the trophy.
To throw a party click on your Sim > Cell phone > and select throw a party. Pick eight Sims to attend, try choosing Sims you are most friendly with because this will help. Set a time preferably one hour from the present time, so you have time to prepare the party. Buy equipment that will help the Sims have a good time like a buffet, drinks bar, balloons, and a stereo system. I hosted the party at the back of my house with all of these items in the garden. After the guests arrive greet them and be friendly to them. Make sure you greet each one at least once.
Buying "Legendary Host" from your Lifetime Rewards, which costs 5,000 points, will improve your guests response to the party. When a few of your guests are arrive at the party use the "Good Times" Karma power (30 Points) which may help improve their response to the party even more. The party will only last a couple of hours and you can save before the party starts, in case you mess up, to make it easier.
