Fantasy is a broad catagory,

But I am fairly certian xenogears would be put in a particular genre I have read before. This genre is called Science Fantasy, more or less a mix of straight Sci-Fi and straight Fantasy. So magic AND robots, which xenogear has.

Some things that the game has in it are plausable, but others are not, which once again fits the science fantasy genre. Anyways I am droning, and if you doubt me of the existence of the science fantasy genre, take a look at what Chris Wooding's early copies(don't know if they are still labeled the same) of his Broken Sky Series, namely I remember the first one being classified as such.


So to answer the question directly, it is niether, it is a mix of the two, and I think it is a fairly even mix that could be argued either way, Although I would say it has more science in it then fantasy(the oposite of The Broken Sky Series)
