Like with Uncanny X-Men 150, what the 200th issue does is not without precedent.
I didn’t come onto Uncanny X-Men until much later. While I started around Gambit’s first appearance, I got back issues to 244.
The Claremont era of the X-Men titles was truly groundbreaking. It not only defined an era of comics, but it also influenced the medium for decades to follow. Due to the nature of the industry today, we will never see a run like that, or many others, again at the Big Two.
