I’m really enjoying Crazy Taxi Gazillionaire, but as a person who’s never played any sort of Crazy Taxi game before I need someone to answer one question for me: What the hell does “What’s the German word for that upgrade feeling?” mean?! Characters keep bringing it up, and it seems specifically designed to stymie Google. I’ve learned about all sorts of useful German words we don’t have in English, the Crazy Taxi games, actual crazy taxi drivers, taxis getting more efficient, and anything else in the venn diagram of the concepts: German, Taxi, Crazy, and Upgrade, but I can’t find anything to tell me what the word is (assuming it’s not just a joke) or any context about it in Crazy Taxi games (joke or not).
Help me Waypoint community: What IS the German word for that upgrade feeling?
