Halo.

you mean some alien race? I rather mean the entire game should be in this kind of language

Then you should only really include Panzer Dragoon Zwei. Saga only uses the language created for the second game in the intro sequence, for the rest of the game they use Japanese. I believe the first game actually didn't contain a made up language, just some jibberish, but I could be wrong.
