The 10 most spoken languages at "I am not allowed to use URLs (sucks) " cover about 50% of all people:
1. Chinese1,197,000,000
2. Spanish414,000,000
3. English335,000,000
4. Hindi 260,000,000
5. Arabic 237,000,000
6. Portuguese203,000,000
7. Bengali193,000,000
8. Russian167,000,000
9. Japanese122,000,000
10. Javanese84,300,000
So, I go for these 10 plus the easy ones that I more or less speak.
Problem remains manual translations. Google translation mixes nouns and verbs.
e.g. "3 jumps" is translated wrongly asif "he jumps" . However, "three jumps" is translated correctly.
The point is that the target description in my game (redacted by Moderator)contains phrases as "33 jumps", etc.
So, having this correct in Mandarin will be nice puzzle ;-)
