CHICAGO – “Final Fantasy XIII-2” takes an adjustment. It’s not that distinct an experience from other “FF” games but gamers currently handling “Modern Warfare 3” or “Skyrim” addictions will have to get accustomed to a very different gaming style. The first couple hours, heavy on cut scenes and with a first level that seems frustratingly juvenile and pedestrian, disappointed me. And then “FF III-2” got its hooks into me. Give it time. Get used to not just the changes within the “FF” franchise but from games you’re used to playing. You’ll probably fall for “FF XIII-2” like I did.
