I don't agree, OP, that the story isn't important at all. It often can be, especially when you play games that are designed to feel like interactive movies.
If you play MW2 and Halo 3 all day long, than no, story likely no impact on your experience as a gamer. Simply because the majority of players play for the awesome and competitive multiplayer experience. Could you like MW2 or Halo for the story? Sure, feel free. But statistically speaking you're likely to give a rat's ass about the story.
If you play ME2 or Heavy Rain or just about any single player campaign, story has at least some relevance, again speaking statistically and generally here. And with a game that essentially
is and interactive movie like ME2, it can be very important.
What it comes down to, however, is simple internet politics.
i.e.:
1. I like games which feature X,Y and/or Z.
2. does not strongly feature X, Y and/or Z.
3. I do not like .
4. Because I do not like then they are inferior to me.
5. .
If you try and follow that logic, you will find that it doesn't make any sense. For some reason, people seem to think that their personal preference is somehow more important than another person's personal preference, or they mistakenly believe that everyone shares their preferences on some level. When we realize that arguments over how important the storyline is to game essentially boil down to the rational equivalent of "Red is the best color!" then we understand how utterly stupid the debate is.
And so on. There are all sorts of other categories which cause one person to like a game and another to hate it. Graphics? Some people really want games that will push their high end system to it's limits and immerse them. Some could care less. And that simple difference in preference is fuel for an equally retarded argument over the issue.
My final thought: there are also a large number of Yahtzee sycophants here at the Escapist, who mimic his every opinion, including the opinion that the single player experience should stand on its own or even trump the multiplayer experience. Which is utter nonsense to many of us gamers.
