Excerpt: Okay, so the Gradius III part of the package looks like an old Super Nintendo game. Gradius IV has a tighter look, one that feels both more hand-drawn and more rendered. It also uses a polygon or two, unlike the strictly sprite-based Gradius III . Neither of them are exactly taxing when it comes to processing power, although I'd imagine that GIV can get pretty tough at times, especially in the later levels. The point I'm trying to make is: who cares?
