X-Men originally tackled a lot of stories from around its years of airing and before - if they are taking up where they left off... we know how Gambit-heavy the mid to late 90s were for Gambit as a solo act (I think 3 solo/duo books?). Including his centric stories we can look forward to adaptations of; Operation Zero Tolerance, Magneto War, The Trial of Gambit, The Hunt for Xavier, Revolution, the Neo conflict, The Twelve... that's just random storylines from the late 90s. That era was very different from one the OG series was based on. Less centered around Cyclops' leadership, more fluid.
