Ok. Thanks. I'm actually working on a huge Traits list and am using a lot of info from here. But also from guides and my own gameplay experiences. Will give credit to this site once it's finished. http://www.snootysims.com/thesims3infoindex.php?id=traitsbiglist
The prima guide is full of errors. The possible reason is that the guide was already finished and then EA delayed the game. Prima then just slapped another cover on it and let the original contents intact.
As for traits. Good and Friendly, Evil and Mean, Loser and Unlucky, Brave and Daredevil are also way too similar.
Very nice guide. One thing I'm wondering, is there a way to make REAL custom paintings? Like put a picture of a porche in some folder and the sim will paint it?
You won't get inapropriate behaviour from Sims you visit if you tinker something there. For example, as a joke, I changed the doorbell on my neighbor into a very silly sound and they didn't react to my banging on their door with a hammer.
If you use the testingcheatsenabled true cheat and shift-click the mailbox, you can change your career and any joblevel. You can get all the special items this way.
For my site, I had to check all the upgrade options. Still don't have all of them but at least I can confirm the following: better food quality at stove is indeed 7 Auto light fireplace is indeed 7 Boost channels for tv is 7 but I suspect it's different with each tv. Expensive tv's may already have more channels. Improve graphics for PC is indeed 8 Wire house with speakers is indeed 8 Faster cooking microwave is 7 (I really didn't see a speed increase though). Trashcompactor is indeed 6
As for unbreakable (6) and self cleaning (3); It's for all objects the same.
After checking, I found that I could Tinker almost every object in that list with just level 1. And my Sim didn't even have the Handy trait. With level 1, I started tinkering the shower and it got Unbreakable. Not sure what's going on there.
