There are hidden wrecks over the island for you to find and a ton of side missions where you do stuff like drive people places and deliver things. You have 25 championships to win and each one has multiple races to do. the islands are huge and the first game really was one of the first open-world racing games, but this tries to take things to the next level. Some challenges can be tricky, but for the most part, I never found myself having too much of a hard time getting past anything the game threw my way. That is not because it is an arcade racer, but because the AI acts like it always wants you to win. The overall gameplay on offer in Test Drive Unlimited 2 is not challenging. By this I mean you can still take corners at a fast speed, but you still need some driving skills and when you get a new car it does take a while to figure out how it handles. The thing is, it does also have sim elements. When it comes to the type of racing that this game offers, I would say it fits more in with arcade-style racers.
The soundtrack is done via two radio stations and while some songs and radio chatter do repeat, I thought this was done pretty well.
The game features two islands for you to race on and they each have a cool paradise kind of style to them.
