If you came from an alien world and had to evaluate our culture based solely on our MMOs... well, you'd probably conclude unpleasant things about our culture, but that's not the point. You would certainly come away with the impression that one of the most important hobbies we possess is fishing, considering how many games it shows up in. Nearly any fantasy game (and several others) will give you the opportunity to stand next to a body of water with a rod, cast your line, and wait for a while until a fish bites.
Or until you realize that you're paying $15 a month to play a game that accurately simulates how mind-numbingly tedious fishing can actually be.
Do you like fishing in MMOs? For some of us, yes, it's the sort of thing we look at once or twice and swiftly conclude isn't what we'd like to spend our time doing. For others, however, the calm and tranquility of just standing by the water, taking a look at the virtual landscape, and relaxing a bit is a welcome change from the pace of the game as a whole. Do you prefer when it's there, do you miss it if it's not, or are you completely uninterested in fishing?
