Whoa, 500+ cars, nice. That is way better than the last time they did a series reboot with FM5, it only had like 200 cars at launch. That is also more than FM6 had on launch, it had 450. We shouldn't have the FM5 issue of low reviews due to lacking content then.
Edit: Nvm, only 20 tracks at launch. That is only 3 more than FM5 and 2 less than FM6, that could definitely hurt reviews some.
