I don't consider CITY to be the same as the old TOWN theme from the 70s-90s. I think Ninjago is actually a top contender for the longest running LEGO theme, because most Castle and Space themes lasted 3 years at the most. (even though most of the subthemes of each theme were connected in the 80s/90s)

By the way, Classic is a recent theme that was introduced around 2015, you might be confusing Classic with BASIC.
