I seem to rarely play games anymore these days, and if I do play a game, the FF13 trilogy is probably not going to be the one, not for any time in the near future.
I played 13, and I played its sequel, and meh and eh are about right descriptions for both of them. Lightning Returns has me curious, because at last they're doing new and interesting things and pushing in new directions, but I don't know if that's enough, particularly when I really just don't care for the world or its characters.
It is puzzling to me how Square can struggle so much at creating a good action-rpg, when they already essentially perfected the formula way back with Kingdom Hearts. Take that battle system, build a half decent world and characters and plot, and avoid any major fuck ups and you'd have a killer game. Instead we somehow get 3 versions of FF13.
