And it's not Stan Lee-era narration of the action, either. Where Thing says, "Darn, I missed!" when he, you know, misses. It's commentary, exposition, and characters just, you know, taalking and thinking in character. It appeals to the roleplayer in me, who can spend an entire scene just talking in character without any actual plot happening. Though there's plenty of plot in Claremont's X-Men too.
The real object of my quest has been to find out the moment in which Kitty Pryde actually used the "Ariel" codename, which Xavier proposes to her but she rejects way back in #139. All the sources say she switched to Ariel in #171, but I have read every page in that comic three times this week and nowhere does Ariel appear. In #169 she says she doesn't like "Sprite" any longer, because it is "a kid's name," but she doesn't use Ariel anywhere in Uncanny until she leaves the team post-Secret Wars and has her miniseries with Wolverine, which is of course when she switched to Shadowcat.
I still maintain that Claremont lost me as a regular X-Man reader when Storm went punk. The whole conversion and change Storm went through was a big non-starter for me, I was totally on Kitty's side during that whole series, and I'm actually kind of surprised that I could read the book when Cyclops -- whom I have always liked -- was getting pooped on and treated like garbage, but when they turned the weather goddess into an ad for Love & Rockets, I quit. Reading the books again today, I still felt exactly the same way.
