The Extended Coaster comes with the RCT3: Wild! expansion pack. The track is styled after Bolliger and Mabillard roller coasters, and is popular due to the large array and versatility of pieces included.
Because of this, the Extended Coaster is popular among Creators and CTR makers, thanks to the range of track pieces available.
All track pieces that come with the extended coaster were accessible with the standard RCT3, but they could not officially be used together until Wild! came out.
Of the different in game cars available of Extended Track, all are B&M style cars except the default "Drifting Coaster" car which is based on Maurer Sohne's X-Car design.
It is also one of the few coasters that can do over 90 degree drops.
