It was readable to the end, but got predictable fairly early on. Plus, the outrageous shounen-like hijinks at the end killed the flow for me and made it feel not so "Gundam"-like. While it wasn't really bad or anything, I felt like the bonus preview for" Kidou Senshi Gundam - Orera Renpou Guren-tai " at the end (bonus chapter 8.5) was more exciting. Doesn't hurt that the GM Striker is my favorite GM suit.
All in all, this is kind of like a male / mobile suit version of "Girls' Last Tour" (at least at first) but less well done, and with more of a battle focus.
