In this era of incredibly sharp graphics, titles that pack multiple textures as well as shaders and other visually intensive elements, it's easy to overlook games with a much simpler presentation. Some of these titles have managed to gather a cult following, primarily because the gameplay is engaging and there's a lot of depth. Take the indie game N, for example, which was released in 2004 by MetaNet Software. A simple puzzle platformer with a large amount of depth thanks to its gameplay and its included level creator, N has become a cult hit for computer owners. Now, Silverbirch Studios and Atari are bringing this classic to PSPs with their updated sequel, N+.
