"Final Fantasy XIII became a controversial game when it was launched in 2010. It was a new take on the JRPG genre, which was odd for a direct entry Final Fantasy title. This caused many to debate about it being a step backwards due to the various issues such as the linearity in gameplay. With this in mind, Square Enix introduced Final Fantasy XIII-2, a re-take at the fresh, although imperfect new formula for the venerable series." - JPS
Sounds like a welcomed upgrade from XIII
