Scotty was a deadbeat.
That's the biggest thing I never liked about Cyclops (and I'm saying that as a Cyclops fan).
The one thing worth pointing out though was that a lot of IRL interference started creeping into the stories around that time.
Scott walking out on his family was an editorial decision that was made behind Chris Claremont's back.
After Jean died at the end of the Phoenix saga, the OG plan was for Jean to stay dead permanently and for Scott to quit the X-men , start a family, and move on with his life.
Later on however, the editors backpedaled and retconned Jean's death on the moon so they could market a spinoff comic about the OG X-men getting back together (X-factor).
That move really derailed Scott's character and ruined the impact of Jean Grey's sacrifice in the Phoenix Saga. Terrible writing, IMO.
That's actdually when I started comics. Basically that 90s Xmen show was based on 80s Xfactor and Xmen shyt. He was one of my favorites during that first 1/2 X-factor run with that husband/wife team (Simpson?)
