Lord. We're lucky we're not having any of these problems with GTA IV. Unfortunately, plenty of people are still getting lock-ups with the game, and some have created a YouTube page dedicated to the issue. From the site:
this is page is here simply to chronicle the freezing epidemic and let naysayers see that this epidemic is very real and very universal. people have lost not only 70 dollars on a game but their entire systems and will now have to spend more of their hard-earned money on replacements, due to a faulty product from rockstar games, which is appauling [sic].
Take a look. There are a lot of videos of the game, like, not moving.
