I choose Naughty Dog as my Company Name , but i didn´t get the Fan Achievment unlocked 
Any Tips ?
Naughty Dog isn’t included in the code. Sorry 
Oh
So which Company Names are included ?
The ones i have used are Sierra, Black Isle and Bethesda.
Some of us have been naughtily decoding the codes and we found these names :
Just look at the achievements “Fan” for the names.
If you take a closer look in the code, you can clearly see there is Naughty Dog in it. A bug maybe? Can you please take a screenshot of your company’s name in the saves? If you typed a typo, it won’t work.
You assume the wiki is 100% correct? 
Yes. As they say…
Wikipedia and Wikis are the truth.
Or so they say.
Yeah, maybe a bug…
