If at first you succeed, churn them out until long after everyone is sick of it...
You can't really blame the games industry for wanting to cash in every year with a new version of its latest successful, proven, low-risk franchise, can you?
Of course you can! If you're a gaming purist - sustaining a successful franchise, particularly if the publisher feels it needs to be updated every year, has got to be a cynical exercise in sacrificing quality for profit.
Although there have been rare examples of franchises that haven't become appreciably crappier as they have progressed. But surely the following have been milked to death?
1. Call of Duty
2. Final Fantasy
4. Resident Evil
5. EA Sports Game (FIFA,NBA,Tiger Woods, Madden)
6. Leisure Suit Larry
7. Street Fighter
8. Tomb Raider
10. Football Manager
