Sorry,if the game doesnt have good ''shaders and all that crap'' than it cant be considered a graphically impressive game.
This is graphically impressive
That top game isn't impressive at all, it looks dull and bland. The bottom one, Muramasa, looks vastly superior.
Graphics = visuals, not just tech. Great tech is irrelevant if the end product doesn't look good. Metroid Prime 3 looks better than most 360 games, hence it is more impressive.
