How about the crappy 'eat dots in a maze' age. It's not like Pac Man didn't have 90 gajillion clones.
There is no good or bad age or genre, really. They're all a mixed bag. For every original game out there, there are 50 clones. For every good game, theres 50 bad ones. It's always been that way.
That said, there's a whole slew of games which are popular just because they're popular, not because they're good or fun games. That Pac Man marketing blitz midway pulled off in the early 80s has really stuck with us.
