The Xbox 360's lack of a guaranteed hard disk is creating limitations in Grand Theft Auto IV's development, Rockstar has acknowledged.
During an interview with our partners in crime at Official PlayStation Magazine, Rockstar's creative vice president Dan Houser was asked: "On PS3 you've got a guarantee that every machine is going to have a hard-drive and, with Blu-ray, you've got plenty of storage, whereas on Xbox 360 there's no guarantee of a hard-drive and you're working with the DVD format. Does that create limitations?" To which he replied, "Yep."
He continued, "To be honest with you we haven't solved all those riddles yet." The difficulties aren't limited to working on Microsoft's box, as Houser explains that "both have enormous challenges" and that "both have their own particular pleasures and pains".
Rockstar hasn't said anything about a target SKU between the two consoles, but they're currently demoing the game to press running on an Xbox 360 - so we wouldn't worry too much if you've only got Microsoft's console. Look for more on GTA IV in the next few weeks.
