Over all, Gamespot’s U.SaGa section seems to have a good amount of images. Including extremely large version of the character profile images. And of course several art works images.
It may not seem like much, but it’s way better than a lot of sites if you ask me. Ah well the game will be out in July. Maybe by then someone else will have something besides images already at say Gamespot…
Still it’s too bad the movies of U.SaGa there require one to be part of the complete version.
