Fan of the series since the first time I was really disappointed with FFXIII, while I had even bought a preview. This game was quickly tiring, sometimes ridiculously difficult, sometimes too simple. Added to this was a series of corridor. So yes it was nice but for the atmosphere FF could use some work. The exploration was non-existent, the interesting characters but not really dug, this being due to the scenario that placed us from start to finish in a situation of flight.
The XIII-2 is really quite the opposite of XIII. The errors are corrected the previous album: Finished hallways, finished linearity, the fights are more fun thanks to subtle arrangements ... The possibility of time travel is quite surprising for the scenario of a FF, but once the system took over, we let completely engulfed by history. It is ato me of a UFO in the series, but a successful UFO!
