Kazuma Kiryu left the gangster life behind and when Yakuza 5 begins he’s working as a taxi cab driver in Fukuoka. Of course, Sega took this opportunity to make a taxi driving mini-game, but Crazy Yakuza Taxi this isn’t.
When players pickup passengers like drunken salarymen sometimes they’ll talk to Kazuma about their problems. You can choose how Kazuma replies to help resolve their issues.
Yakuza 5 also has race battles where you zip through a highway and try to beat a rival. Players can drift around corners and do roaring heat actions (kind of like regular heat actions, but in a vehicle) to win the race. Sega made a car customization feature too where you can choose paint jobs, add decals, and tune a taxi by changing tires. Check out screenshots of race battles over at Famitsu.
