Y'all can poo-poo this if you want, but I'm having lots of fun. Calling it a "Crazy Taxi" mode is a bit disingenuous. I mean, it's obviously heavily inspired by it, but yes, the vehicles don't control like Crazy Taxi at all. Vehicles in Fortnite are slow and heavy unless you're driving the top tier sports cars, and these aren't those. On top of that, I feel like Season 4 has changed how Fortnite's vehicles handle so they flip and roll a lot more easily when you make sharp turns.
But like I said, I'm still having fun. The idea that passengers make requests for you to do specific things for bonus points is brilliant. Like some passengers want you to get lots of air, or ram in to other vehicles, or drive offroad for a specific amount of time, etc. If Sega were to ever make a Crazy Taxi 4, that's something they should definitely borrow.
The annoying thing is when you get in to a match with people who remember Fortnite is a shooter. You can get out of the taxi and shoot at other vehicles if you want, and as someone who's just there to drive around picking up and dropping off fares, it really, really sucks when somebody's running around with a grenade launcher ruining my (and everyone else's) day. Dirtyshubb is right, too -- once you fall behind in points it's basically impossible to catch up.
Still. Knowing Sega, this is probably about as close to a new Crazy Taxi game as we'll ever get.
