The wall block of claim 1 wherein the total number of the at least one lip is two and the total number of the at least one recessed surface is one. 6. The wall block of claim 1 wherein the block body includes opposing first and second side surfaces and wherein the exposed surface of the front face has two or more vertically orientated surfaces, at least one vertically orientated surface extending from the first side surface to the second side surface of the block body. 7. The wall block of claim 6 wherein at least one vertically orientated surface of the exposed surface of the front face is closed to the first and second side surfaces of the block body. 8. A wall block system comprising: a plurality of blocks including first and second blocks, each block having a block body including a top surface, a bottom surface and a front face having an exposed surface and at least one recessed surface, each block further having at least one lip extending from the top surface, the at least one recessed surface being formed into the bottom surface and front face, the at least one recessed surface being set back from the exposed surface of the front face into the block body, the at least one lip having first and second ends, first and second lateral surfaces and an upper surface, one of the lateral surfaces forming a part of the front face, the at least one lip having a length as measured between the first and second ends, a total number of the at least one lip not being equal to a total number of the at least one recessed surface;the at least one recessed surface being sized such that when a wall is formed from the plurality of blocks stacked in multiple courses at least a portion of the at least one lip of the first block positioned in a first course will be accommodated in the at least one recessed surface of the second block in a second course overlying the first course and wherein the at least one recessed surface of the second block in a second course engages a lateral surface of the at least one lip from the first block positioned in a first course. 9. The wall block system of claim 8 wherein the total number of the at least one lip is one and the total number of the at least one recessed surface is two. 10. The wall block system of claim 9 wherein the length of the one lip is greater than a length of each of the two recessed surfaces. 11.
