Question
Since the advent of polygons to draw game objects and move gaming fully into three dimensions, there has been much debate about whether certain games would be better using sprites instead of polygons. For instances, many "2D" fighting games, games in which players only move in two dimensions, are moving from traditional hand-drawn sprites to rendered 3D models using polygons. Choose a game that uses one of these techniques (polygons or sprites), and detail why you think it would be better if it used the other. Reading the posts from the other students, reply to at least two and describe whether you agree or disagree with them.
