A lot of Hollywood studios have been scraping the bottom of the barrel for a long time. It’s the same with novels. Same story with perhaps a different setting and a change of character names. Pro writing guides even encourage it. One I read said "there are no original ideas, the trick is to add some innovation to an already existing story." Good to see such healthy optimism..
Anyway, games are still young and luckily have a good bit of time until we start to dry up.
As for the Bioshock movie.. meh, I’ll keep an eye on it.
