Really great game. While not quite as refined as Zero 2 or 3, the core gameplay and level design was still a lot of fun. However, I did find some of the changes and new mechanics a bit disagreeable though. The part system managed to be almost as obtuse as X5's, the new cyberelf system removed the fun of collecting them, the change in EX skill acquisition was dumb, etc. The removal of elemental chips was genius though, as it alleviates the franchise's long-standing issue with weakness abuse sucking the fun out of bosses. Serves as an amazing epilogue to the Zero series, too.
