Yet, Dragon is still going over a decade later - throughout that time dozens of major characters have been killed off, countless new ones introduced, Dragon joined a government run superhero group, his Earth was destroyed, he was sent to an alternate Earth filled with Kamandi-esque mutated insects and animals, he got married, his wife was killed, and his children have grown into young adulthood and are having "adventures" of their own (this is just what I can recall off the top o' my head - there's been much, much more).
Larsen hadn't run out of ideas back then (he was just getting started!) and he certainly hasn't now.
