It's pretty impressive - a full translation of all text and voices. I've only started playing, so basically only got past the intro, but it's cute in a strange way. Some of the translations are weird, and IMO, not very accurate, but the entire thing is still very professionally done.
With Israel being a rather small market, full translations such as this one are not very common; to the best of my knowledge this is the only game in the primary Rayman series that got translated to Hebrew (the Hebrew version of Rayman Junior is a different manner, as it is more of a learning program than a game).
The game is based on the early 3-CD release, not the later 1-DVD one; it uses its own product code, so it can be installed side-by-side with the English version, which is cool.
- Globox's name has been changed to 'Mogul'. No idea why. None of the other main characters mentioned in the manual had their names changed.
- They obviously could not translate the lum-hoodlum pun, but instead of trying to find some alternative play on words, they just translated 'hoodlums' to 'mega-lums' which makes no sense story-wise; the full title "Hoodlum Havoc" has thus been translated to "Mega-lum Revolution", but I confess I don't know of a good word for 'Havoc' in Hebrew.

I'm now playing through the Russian version and updating with various discoveries about the translation. The start is in this post.
