Well, FFX feels more like "fantasy" while FF13 feels... not?

FFX is linear but you can progress to past towns, you get an airship to visit other places(not like FF9 and lower) and the party as a hole is better, even the story is better, the music is better, more side quests especially if your going for international.

NOw what does FF13 have better?
A harder difficulty, extreme graphics, better overall sound quality, but in terms of a lousy party.
