Monster trucks + Formula 1 = Formula Fun!!!
The World tour is split into tiers. In each tier you have a choics between a certain amount of championships. You have a quite funny scottish manager called Rick. He will talk about how to drive certain cars and so on.
This mode is the main mode of the game
Also there is the Pro career. In Pro career you have to do all the events in a specific type of racing (e.g Oval or open wheel). You don't have the cut scenes in this but its alright.
Toca is enormous fun but you feel they have cut corners here and there. There are 35 different motorsports and this means there aren't very many championships in each one. And alot of the 35 motorsports are no name motorsports anyway. The Nascar is missing. You don't get proper FI. You only get BMW williams and not all the other teams. Most championships only let you drive one car.
Still despite that Toca 3 is a great laugh. The multiplayer is great aswell. Multiplayer monster trucks! Hilarious! Toca is the Ultimate Driving Simulator!
