Scenario
Ben Bitdiddle challenged Alyssa P. Hacker to a Persona 4 Arena match. Ben bet $10 that he would be able to beat Alyssa, but recently discovered that Alyssa had suckered him and was pretty good at this particular fighting game. Determined not to lose his $10, he turns to the internet to search for fighting combos that he could easily learn as a novice fighting game player. The first few results reveal a slew of forum posts that are totally unorganized. He gains no sense of how difficult any particular combo is and the notation for the combos is confusing and foreign to him. And then he stumbles upon his saving grace: Combopedia.
Immediately he identified the character he would be playing as and was presented with a list of relevant combos. Each combo had a difficulty rating and its own discussion thread, which he could use to identify which combos were more general-purpose. To his great relief, the foreign notation that he had encountered in the other forums he had visited was supplemented by a graphical notation which easily mapped to his controller. Some combos even had videos which helped him understand the timing of each sequence of button presses!
Armed with the information he gleaned from Combopedia, he entered his match against Alyssa with confidence. While he still lost, it was by a much narrower margin than it would have been otherwise, and he was not completely ashamed.
