games expressing unified design (worth playing)

Certain games have expressed something to me more distinctly than others. The expression isn't as narrow as a single emotion, but it feels more introspective and intentional than the broad assortment of procedural rhetoric necessary to make an action game coherent. I feel that these games manage to make a few elements amplify the meanings of each other, and successfully leave distracting additions and unrelated details behind. They seemed to be designed conservatively by starting with a concept and then building off of it's inherent logic.
