Well. If you want a 5/5 challenge, fire up Shenzhen.io and set the language to Chinese. It seems to be beautifully translated to my limited ability to discern, but boy is it hard to learn enough Chinese to play the game! Difficulty: 5/5
Ironically, in China some gamers complained that the game is kind of unrealistic as all the datasheets are available in Chinese, it shouldn't and it has made the game less challenging... In real life, engineers in Shenzhen rarely read or write formal datasheets in Chinese, even when the IC is completely designed in China.
Doing it in English can be a bit difficult for a freshman who is unfamiliar with the terminology, which can make the game a bit more interesting. I wonder if the developers should add a "native language w/ English documentation" option for those who want a more authentic experience.
Heh, I'd count it unrealistic if all the datasheets were available in any language. As much as I rag on Google sometimes, Google Translate has been very useful from time to time.
