Hrm. I would definitely be exponentially more interested in XV if it had playable female characters, because I've always enjoyed playing as them more and that's my personal preference and always will be. So as far as it being an all-male cast goes, I think it's unfortunate but it's not damning. As mentioned earlier, if they actually take a few steps forward and write a decent romantic plot between some of them, I think that would be really cool.

What I am much more turned off by is the oversimplification the game seems to be getting in that you can only directly control one character. What is this, Persona 3? (And even then they fixed that nonsense in the PSP reboot.)
