Inventing

The Inventor career, which will appear in the Ambitions expansion pack for The Sims 3, may be related to the Science career, though, it's expected to be a completely new job. Sims will need to have a high inventing skill, which will come with Ambitions also, to get promoted often. With it, Sims will be able to build for example: floor hygienator (provides hygiene to sims who walk over it), toys, widgets, a personal drilling device, a time machine, and even a personal robot. These inventions (and other things) can be used to complete opportunities or be sold via the consignment store for a handy profit. As an inventor, your sims can create either brilliant or destructive gadgets.
