Time machine

The Time Machine is an object in The Sims 3: Ambitions. It is created with the Inventing skill. It will be about the fifteenth invention of your Sim and it requires inventing level 9.

The exterior look of the time machine is most likely based on the one seen in Blackadder: Back and Forth. The Time Machine is a rabbit hole similar to the Mausoleum. A Sim can return with various items including a caveman gnome, much as the original Mysterious Mr. Gnome is discovered in the Mausoleum.

It's possible for Sims to meet their previous selves and/or previous companions, and tell them to stop fighting and focus on love and family. If this happens, a Sim may suddenly have a child, but the child will only have one parent. When a Sim travels to the past, he or she can accidentally knock over a job board. If that happens, when the Sim returns, one of his or her housemates will have switched careers. Occasionally, traveling to the past will result in a message about the Sim using the machine having saved a child in front of his or her past self. This results in a new child being added to the household.

The time machine also makes a quick reference to Mass Effect when it says that the Sim was passing a crowd, listening about a shepherd (Commander Shepard, the main protagonist), saving the Galaxy from an ancient god threat (the Reapers). Additionally, the futuristic outfits that can be gained by going into the future highly resemble the Spectre Armors that can be acquired in Mass Effect.

It is thought that the time machine will feature in the console versions of The Sims 3: Pets.

Effects of time travel
Traveling to the past can have huge consequences for a Sim's household (new job, new friends, new Sim in the household), while traveling to the future seems to be more harmless, though the Sim sometimes comes back with an object or moodlet. It is also possible for a Sim to return from a time travel trip with a new outfit related to the time period he or she traveled to. There are 4 unique outfits for each gender.

Both

 * Positive or negative 'Traveled in Time' moodlet. (Bigger chance of getting positive moodlet if the Sim has the Adventurous and/or Brave traits)
 * Random other moodlet.
 * Cash. Between §81-§2487.
 * New clothing (including a rusty set of armor and a futuristic suit).

Past

 * New career for random member in household.
 * 3 new friends of the entire household.
 * A new Sim joins the household as child of the time traveller, though the infobox will say ancestor. (Edit: sometimes they are adopted so they'll be son/daughter with a single parent.)
 * New outfits: Prehistoric rags and Medieval attire
 * If the Sim is a ghost, they may get a message saying "[SIM'S NAME] went back in time to see how they became a ghost, but accidentally changed events so they never became one! [SIM'S NAME] is alive again!"
 * If the Sim is a mummy, they can prevent the invention of mummies and will be cured when they return.
 * Slight possibility of the Time Machine getting hit by a huge meteorite happen 3 times to account for it to be plauseable.

There is one recorded vent of woohooing in the time machine.

Trivia
Time travel has previously been featured in the mishap that brought Don Lothario to Riverview, and the time machine is available for use in The Sims 2 for Nintendo DS.

It also appeared in The Urbz: Sims in the City for Nintendo DS and Gameboy Advance as a strange machine. The player should go in 5 different times, each having a different area. One of the outfits from the future resemble the clothing from Tron.
