The first issues of Cable are set after the first 16 issues of X-Force, too. Issues 99-100 of New Mutants have been reprinted loads of times, most recently in a Shatterstar trade. Issue 98 not as much, if ever. Issue 87 has been reprinted hundreds of times!
It's right 87 has been reprinted. New Mutants was a big huge mess at the time. Liefield and the Cable character really breathed life into the title. I was there, I know. What happened after that though ..... we get an entire issues storyline just dropped - big jump from the end of 91 to the start of 93 (thee's a fill in issue as 92) and a very abrupt opening to 93 which makes you think they'd plotted a proper issue 92. Then Liefield's contributions to Extinction Agenda are either badly inked. sporadic or non existant. Fortunately those last 3 issues are good.
Trade Paperback List say that NM98 hasn't been reprinted in trade format before, so I guess it makes sense to put it in the Deadpool trade. Which I really hope they continue with, Deadpool back issues are damn hard to get, and the good stuff is really after what they're putting in that first trade.
According to my new favorite site (Thanks James) tplist.millarworld.net/xmen.html#newmutants the Cable 2nd Genesis volume has both of these and X-Factor 1. I now need a copy of this. I don't suppose a certain Charring Cross Rd based comic shop could supply me with one ?
Essentials 8 is rather good, I don't have fond meories of what I expected was within. But the Leonardi fill in art is much better than I thought in my teens now it's reproduced in B&W and as a bonus there's X-Men Annual 12 with some blinding Art Adams wiork that looks soooo beautiful without colour - check out the big splash page of Terminus. As a bonus it doevtails nicely with the end of the last X-Factor essential.
