You chose to go for a Single Fight, because you had other stuff to do that day besides playing an entire international fighting tournament in a video game that you just bought, and you liked the characters you already have. You played on easy mode, and you remember all the combos the characters to perform fighting moves.
As you get to the characters list, you take a look at all of the characters the game had, and each character had a different location from around the world which is why the game would be about an international fighting tournament. The male characters were pretty beefy compared to the sexy female characters which turned you on, and gave you boners. You decided to choose one character for a quick fight, and then do something else for the rest of the day while you were still up.
