What games could not have been done last gen?

Really good thread!

I'm probably in the minority on this, but I think most seventh generation games could have translated to machines with older technology. For sure they wouldn't look or sound as good, and they wouldn't be as capable of more sophisticated artificial intelligence, etc. But the core gameplay could be reproduced a generation or two earlier. All the bells and whistles would go missing, so I guess it depends on how important those bells and whistles are to each player.
