Dum question

Is there anyway that u can translate a whole game into english

1.yeah pretty stupid question
2.yes if the company wants to (think maplestory) if somebody else then its illegal

That was kinda silly.
but could possibly be done. 1/100 games.
if the game your playing has some .txt files in it,
you could run them through the google.
but if you slip up.
you'd have to re-install the game
and still play the bloody thing in the langauge,
that the programer set it out in. <- a ramble on nothing. :D

It's not exceptionally hard to inject translations into a PC game, but still requires a lot of PC-related knowledge, as well as a large time investment, multiple people who are fluent in the language from which you are translating, and vice versa.

It isn't something a typical person usually takes on as a project. You often need many people to do it, but nothing is impossible.
