As we told you yesterday, your season calendar fills in dynamically, but there are a series of weekend races that don't change. There are six "standard seasons" in Forza 3, meaning that there are six full seasons with these specific weekend championships. Each season gets longer and harder as, hopefully, you also get better. By the end of the six season, you'll have completed 55 events (some with more than 10 races!), reached level 50, earned all of your gift cars and spent about 60 hours racing. But it's not over. There are still more than 150 unique events to race. And though the weekend championships won't be any different, there's hundreds of hours left if you want to truly complete Forza 3.
Remember that the AI, which looks at the cars you owned, the cars you drive and the tracks you race, determines the majority of events in your first six seasons. If you ignore Drag Racing events, eventually they go away. After all, why offer something you don't want to race? If you stuck with American cars the entire time, there are going to be a number of European and Japanese racing challenges ahead of you once you finish your sixth season. Though you might have mastered all the championships, by the end of season six, you're only a third of the way through Forza 3.
It's like Bullit's famous chase scene, but without cool cars.At any time, you can ignore the season calendar and bring up a master grid of all 220 events. This grid is very similar to the career mode in Forza 2. It lists every open race and, at any time, you can race those. These also feed into the dynamic calendar, because, after all, they are races you're choosing. Never worry that you're going to miss something in Forza 3. There is always an option to break free of the dynamic calendar and race any event for which you're qualified.
