I guess after you play or review a few high-caliber 3D action games—particularly ones with fast, stunning graphics and sound—you sort of become numb to similarly fantastic, over-the-top games. You overdose on them, or at least I do. You need to cleanse the palette, as it were. Eventually along will come a simple game, completely out of nowhere. No fancy 3D engine, shaders, or blazing polygon models. Just clever use of lighting, and in-game ambience that is so darn good, it is like discovering the wonder of your iPad for the first time. Type:Rider ($2.99) is exactly that kind of game.
