The Extra Credits video this week talked about how we keep classifying games based on their mechanics (FPS, RTS, Racing, RPG, MMORPG, Puzzle, etc) instead of their aesthethic values (like drama, fantasy, horror). I guess that's why mechanics always take priority over writing, since many developers keep thinking first about the interface they want to present the gamer and not the atmosphere and experience they want to engage people with. I agree that as long as this mentality persists, writing or storytelling in general will take a backseat to gameplay concerns instead of being developed in synergy. Either that, or once the gameplay is built the "story" is made up to adapt to the gameplay in place, even if it makes no sense.
