When you go to a store and say, "Want to play X-Wing?" and mention alternate formats - HotAC, missions, Epic - the tourney-only players start to get that scared look in their eyes and you can see the wheels visibly turning. "What? Unfamiliar format? I don't know the best builds... is he angling for an easy win? I DON'T KNOW HOW TO PLAY THAT WAY!!!"
More likely they packed their stuff and drove to the store expecting to play a few 100 point games.
Which is because the 100 point game is all anyone ever expects to play, because that's all anyone EVER plays. Because FFG said the standard game is 100 points and no one wants to try anything else.
That's why articles like this are important, to try and get people moving AWAY from exclusively playing tournament format games.
