They match quite well:
Johnny = Thinker
Timmy = Character Actor
Spike = Power Gamer
Vorthos = Storyteller
Thinker: "This kind of person is likely to enjoy min-maxing a character, spending hours out of game to find every conceivable advantage available in the system to deliver maximum damage from behind maximum protection, even if the min-maxing produces results that are seemingly illogical/impossible." That sounds a lot more like Spike than Johnny.
Power Gamer: "This kind of person is likely to enjoy playing a character that has a minimum of personality (often, this kind of person plays a character that is simply an extension of the player). This kind of player enjoys short, intense gaming experiences. The consequences of a failed action are minimized for this player, who will roll up a new character and return to the fray without much thought for the storyline implications of that action." Sounds like Timmy... mostly. I don't know where the heck you see Spike in this.
Character Actor: "This kind of person is likely to enjoy the act of theater; using voice, posture, props, etc. to express a character's actions and dialog. This player will have a character that makes sub-optimal choices (from an external perspective) to ensure that the character's actions are 'correct' from the perspective of the character's motivations, ethics, and knowledge." You can make this look like Vorthos if you squint hard. It doesn't resemble any of the other three.
Storyteller: "This kind of person finds enjoyment from the logical progression of the narrative of the scenario. There should be a beginning, a middle and an end. Characters should develop over time in reaction to their experiences. This player will look for a non-rules answer to inconsistencies or anachronisms in the game experience." There is no parallel whatsoever in M:tG to this.
I stand by my statement. The Rosewater profiles are a terrible fit for D&D.
