Cnet writes: "Film critics have decried the disease of sequel-itis since the Hollywood blockbuster era began more than 30 years ago. They bemoan the lack of originality, the reliance on popular themes and characters, and the sheeplike masses who flock to repeated installments of their favorite franchises. Video games have been onboard with the idea of sequels almost from the very start (remember Ms. Pac-Man?), but the idea of creating cash-generating franchises has taken on new importance in an increasingly hit-driven environment.
So, it's only natural for some industry watchers to bemoan the likes of Mass Effect 2, Halo 3, BioShock 2, Assassin's Creed 2, and others. But, judging from recent experience, the real problem is not that these games share too much with movie sequels, it's that they're not enough alike."
