I've never posted here before so sorry if I'm a noob...

CAS: Create 8 different Sims they can look however you like, but each sim must have one negative trait whether it be hot-headed, gloomy, evil, mean, loner, jealous, or ambitious (the Sims can’t have jobs so they will feel tense if they have this trait).
Build mode: Once you have created your “cast” move them into any lot you want and create a house as big or as small as you would like. Money is not the focus of the challenge, so give them as much money as you’d like. Keep in mind that they will be locked in the house until the winner is chosen so the exterior doesn’t have to be super detailed. Another thing to keep in mind while building the house is the fact that they are cut off from the outside world that means NO televisions, stereos, computer, bookshelves, etc. For entertainment you can place a chess table, pool, spa, and gym equipment. You can also place the VIP Bucket in any room to make sims flirty.

Gameplay: You can set aging to whatever you like or turn it off completely. You may not control any sim unless they are stuck or you may complete a whim they might have at the present moment. All houseguest’s will stay in the house until they are evicted unless they are kicked out of the house because of unacceptable behaviors such as fighting other houseguests.

Week 1, Episode 1: Head of Household (HOH) Competition
For the HOH competition you have a choice of choosing a houseguest randomly, or having your houseguests compete in a competition (e.g. Painting (winner with the highest priced painting wins), chess, etc.).
Ep. 2: Nomination Day
Have the HOH nominate 2 houseguests who he/she has the least relationship with to be evicted on the 4th episode.
Ep. 3: Power of Veto (POV) and Veto Ceremony
For the POV both the HOH and the nominees along with 3 randomly chosen houseguests will compete in a competition (or one of them may be chosen randomly) to win the POV. The houseguest that wins the POV has an option to remove one of the nominations from the block during the veto ceremony.
If the veto winner chooses to remove someone from the block (veto winner must choose nominee with the highest relationship to them (or themselves if they are on the block)). However if they don’t have a high relationship with any of the nominees the nominations can stay the same. If the veto is used the HOH’s 3rd lowest relationship will be nominated.
Ep. 4: Eviction Night
On this night each houseguest (except the nominees and HOH unless there is a tie) will vote for who they want to leave the big brother house. This will be decided based on each houseguest’s relationship with nominees. If they have the same amount of relationship with both nominees you can decide whether to randomly choose for them or let them vote with the majority of the house. The houseguest with the most votes must leave the house after all the houseguests have voted. (7 houseguests should remain)
