Camera angles are one of the often underappreciated good things in a video game. A good camera angle lets you fully view your character and environment. Back in the days of 2D gaming an overhead view was often used along with a sidescrolling view, with the latter of which still being used today in some 2D platforming games. When the 3D era hit, most developers had trouble programming in that third dimensional space. There were many great games once they got the hang of it, but even some of the greats had horrid camera angles.
