Now, normally, I think "/thread"-type posts are annoying, but once I say, "Link's Awakening" and the fact that the whole thing was just a dream, well... That has to be at least one of the worst. At least it was a fun game.
Also, OP, I suggest using the search bar before making a new thread; repeat threads have a negative stigma around here.
Also, when making threads about a certain aspect of the game, don't ask, "what is the most *relative term here* game?" Ask, "Which game do you think is the most *relative term here*". It avoids the inevitable trolling aspect that comes with asking a group to make a decision on something inconcrete.
With that out of the way, welcome to the Escapist, Box oDave!
Edit: Based on the technical term of retardation, (slow), I'd say this: Sconic Labrynth. [http://en.wikipedia.org/wiki/Sonic_Labyrinth]
When you put slow down shoes on a character known for his speed... Well, its technically the most retarded game in the series.
