I have read nearly all of the X-titles including X-Men, Uncanny X-Men, X-Factor, X-Force, Excalibur, and Generation X. I enjoyed all of these titles, but for the longest while I was particularly fond of Excalibur. This was due in part to my favourite X-character being Shadowcat, and due to the fact that Excalibur was the comic that was most readily available to me.
