Hi, i add my voice to the choir of those who wants to have the italian localization of Divinity: Original Sin.
I played Divine Divinity some years ago, thanks to a magazine.
The game was translated by the ITP crew (in italian) and the translation was very good.
At that time my english was very low, and probably i would not played in english; today my english is improved a lot, but play the game in one own language is a different experience, somehow play something in a foreign language implies some efforts that with the translated game you don't have.
Now the new one (Divinity: Original Sin) seems to be a very big game, so i hope that Larian Studios will consider this option.
