On the flip side is Gamer. While this wasn't the worst video game related movie (it beats Stay Alive by a mile), it definitely could have been worse. Basically this Bill Gates kind of guy develops a way to put nanites in your brain so that you can be controlled remotely. He creates a Sony Home type place called Society and a Halo type game called Slayers.
It felt a little like The Running Man meets Deathrace (the one with Jason Statham). It wasn't that bad of a movie really. The action was pretty good. The plot was iffy, but that wasn't a surprise at all.
I like it how Hollywood has discovered nano-bots as a convenient plot device to explain all sorts of stuff in movies.
