I've said numerous times I like XIII and XIII-2. I've recognized a few problems with both, but I've expressed that over all I like XIII and XIII-2 and fully expect to love Lightning Returns. That cover is the first thing I've even bothered complaining about, and I hold that there's just something off about Lightning in that picture. For all I know it could just be that the outfit really doesn't suit her.
But, you know, whatever. I don't blame you that rampant cynicism in the gaming community makes it impossible to express any legitimate complaints.
