CNN is reporting that the Hollywood writers' strike could mean good things for the games industry.
Of course, the article is essentially speculating that the lack of good TV could mean that people will put down their remotes and pick up a controller. There is no real data to support this, but it does make some sense.
I think that all alternate forms of entertainment will do well due to the strike. Video rentals are sure to go up. Movie going may also see a spike (plus there are a ton of good movies out there right now). It would only follow that video games would also benefit.
