Today is the day it's released in good 'ol SA. I'll be going to be pick up my copy today (hopefully).
For all of those who don't know what Crackdown is: imagine a futuristic GTA, with a bigger more open ended world with light-RPG elements! It's made by the same guy who created Grand Theft Auto (and Lemmings), but left Rockstar to form his own company.
It's been getting pretty good scores (oh and it includes the Halo 3 Beta)
