1990's, by far.
It was classic after classic on pretty much every system that mattered. Though if 10 years outside strict decades are allowed I'd say 1994-2003 were the Golden Years. Want to include 1993 but then it would be 11 years... Whatever I'm including 1993.
By the way it's kind of funny you seemingly couldn't come up with anything to describe the 2010s in the poll!
