...its career mode is full bodied. You start out at the bottom of the Sprint Cup series with your own team and have to earn contracts and satisfy real sponsors in order to upgrade your organization. If you take Nationwide, for example, both you and Junior would have the sponsor on your cars (with separate paint schemes) even though you're on different teams. You can also keep your sponsorship at any time instead of upgrading, although you'll always make more money even if you decline a new sponsor.
When you start out you pick your car number, manufacturer, and your avatar (including the ability to have a female driver), and at the initial few races you'll be competing to get payouts from secondary sponsors who have various conditions such as finishing in the top 30, for instance. As you progress, separate challenges from drivers will break up the week-to-week schedule. These will be historic situations from the past few seasons.
There is a big board of upgrades you can earn, from buying and expanding your garage space and engine shop to hiring various specialists, and Monster believes your team should take some time to get to the level of the big race teams. Thankfully, there is no limit to how long the career mode goes.
