Hmm... okay. PoeticJustice has a point; it's been a while since I read the definitions.
So, substitute "Vorthos" for "Timmy" in my posts above. However, while Vorthos's tastes don't really affect Magic gameplay - Mark Rosewater claims he belongs in his own category, separate from Johnny/Timmy/Spike - they have a huge impact on D&D, where flavor actually affects the mechanical game. Indeed, many of the big debates on these forums boil down to a running battle between Vorthos and Spike that's been going on since the birth of the game.
Flavor affects game experience but not necessarily "game"... at least not often or much (I do give boosts to character performance when player narrative syncs particularly well with features in the environment) I have played rpg's where narrative dominated the action resolution mechanics. In comparison to these D&D is and pretty much always has been roll the dice then paste flavor on top of mechanics ( and it used to feel like that part was all the DM's job, atleast now in 4e it actively encourages player involvement.)
And umm if they didnt have cool art and flavor on the entire MTG game premise I would have never bought mtg cards so I dont think the divergence or degree of divergence is what you think...
