Final Fantasy XIII was a very disappointing game: lacklustre game play, whimpy annoying characters, weak story line and plot, too many CGI cut scenes that went on for a long time and extremely linear for a JRPG, no towns to explore.
FFXIII averaged 83% on metacritic but contained mixed reviews ranging from 40% to a few 100% review scores. FFXIII probably only deserved a matacritic score of 70%: soft reviewers, 20+ year establish brand name saved it from getting marked down to the average review score it thoroughly deserved. Lower ranking JRPGs on metacritic in the 65 to 75 review range were better games but did not have the brand name to protect them from getting smashed in the review scores. Final Fantasy XIII did not deserve its sales success and FF fans were heavily didsappointed in a series that has seen better times.
The action in FFXV looks very impressive, a huge improvement upon FFXIII. FFXV game play looked a lot like Devil May Cry, Ninja Gaiden, God of War/hack n' slash. Final Fantasy XV has been converted into hack n' slash- confirmed. FFXV will hopefully bring new life to a series that has seen better days.
