The plot for G-Senjou has a lot of holes but I really really think the lack of consistency made it great for adding the suspense. For a very long time in reading the VN, I actually thought Kyouuske was Maou! I got my first hint that they were seperate people when it went back In Usami's backstory. My main, if not only, problem with G-Senjou was that it was so obvious that Usami Haru's route was the "main" route and the lack of detail all the other routes got. This wasn't a real problem for me because I really, really liked Usami Haru but lack of detail on other routes really make me wish there was some sort of other implementation for all the other routes.
