There's some really badass ideas up there, though I probably would be the first here to say that I wouldn't really like the idea of being a Monster Jam only game, otherwise you would have to put with things like no Bigfoot trucks since Bigfoot does not compete with Monster Jam, and probably may never will. I would honestly much prefer if the game would cover all major monster truck events like the Toughest Monster Truck Tour and the 4-Wheel Jamboree events, not just Monster Jam in general.
I also would love to see a decade menu, which the player can choose which decade they want to compete in. For e.g. the player selects the 80s decade, and it will only display a roster of trucks and tracks from the 80s.
I'm probably asking too much, but as a pure monster truck enthusiast, it would be the ultimate dream game.
