MagizZziaN was referring to the PC version, which works fine between US/UK games/systems. XBox games must match the PAL/NTSC type of the console, so you can not import the UK version to the US, or vise versa.
I have some PAL games that work fine on my NTSC system. It all depends if the game is region-locked or not.
I keep forgetting about Venetica. Are they currently looking for a publisher?
Well, Deck 13 hasn't updated any word on the game in quite a long time, so I'm not very hopeful in it getting a US release. I sooo wish it would.
They do have this in common:
http://www.dtp-entertainment.com/It shows a PAL version on their site:
http://www.dtp-entertainment.com/en/games/xbox-360/game_detail.php?id=3173&landid=1Divinity II dude and Venetica chick right next to each other, so I was hoping CDV would pick up publishing rights to Venetica, too, seeing as they like to publish this style of RPG it seems.
It looks so pretty.

PLEASE BRING IT TO THE US!!!!
I still have a shred of hope since Jack Keane saw a US release, but none of the Ankh titles have (all from the same developer as Venetica).
Hoping to hear word on a US launch in 2010.

Or at the very least a region-free PAL release.
