not to be mean but type "graces" in the gamefaqs search function there's 8 pages of topics so you can get a wide range of opinions/comparisons through those --- 3DS FC 0146 8594 6672-Tin Town: New Eden
Really I feel like Graces has the better content and battle system but my opinion might be in the minority. The character chemistry is also better in graces too. However Xillia is still a great game and has a better story than graces. --- FC: 3480 - 3168 - 8883
better story more difficult to strategize in boss fights (AC plus manage TP) Better character development Better character designs
Less costumes (4 in game rest are DLC) No cameo No mini games No indignation. Not very long alledgedly (Grinds levels til its really slow leveling)
IMO A tad better and more then just graces had but my 'less' and 'noes' are a bit hurtful to myself... --- Seriously... all of these flames are amusing that it's fun to be trolled nowadays, FLAME MORE EVERYONE! THEY ARE FUN! Official Laguna's Ragnarok Cannon of TGAE!
I found graces better in pretty much all aspects except xillia lets you switch characters mid-battle. This is a godsend for someone like me that uses pretty much everyone. --- Visit my youtube page for game and anime vlogs, and plenty of other stuff: http://www.youtube.com/user/BaoZakeruga?show_guided_help=1
I liked Graces, and I found Xillia to be inadequate and worse than Graces in a lot of ways. The gps map is a lot like in ff13, the towns are lackluster, the story is one of the worst in the franchise, sub par VA, monotonous dungeons and overworld. The combat in Xillia is really cool, and frankly gamechanger for the series, but that's it, the rest is pretty trash imo.
