Imagine you're just sitting around. Chillin'. Sipping a coffee, maybe. Suddenly, a Viking lumbers up to you. "Hey," he begins, "How's it going? Listen, I don't know you and you don't know me, but do you think you could, y'know, lend us a hand and save our village?" Of course the only correct answer is "Yes," and given that the Viking exists in the digital realm of Save Our Village, you don't even have to pull yourself into a standing position before committing yourself to these heroic deeds.
