In my opinion i think most people are disappointed by this game as it doesnt meet there expections, of where they can jump on it, and be great straight off, the handling etc takes a while to get use to, you need to practice and build yourself up on the game, which means time and effort, something some people don't want to give,
I am not saying the same is perfect, it's not, it needs some refining, yet jumping onto the simulation mode, does as it should, it reinacts how a bike would handle in the real world. Also some people find a problem with the throttle control especially in the simulation mode, this can be down to actual 'r2' button on the controller rather than the game.
I rate this 5 stars, as well, the game does as it should basically, the graphics are good, it imitates real riding experiences, and provides all classes and riders as well as manufacters
If you want a bike game to race with, this is definitality it, just in career or championship mode, don't expect to to win out of the box
