EA Formula One series

After losing the official F1 licence from FIA to a multi-year exclusive licensing contract to Sony (publishers of the competing Formula One series), ISI developed their final release hitting stores in 2003. Showcasing four full seasons of Formula 1 from 1999 to 2002, many people thought it would be a type of compilation of all the games previously released but in fact the title turned into a cult following for both modders and sim racers.

In its earlier titles, ISI often tended to make mistakes modeling the tracks, cars and sounds, but for F1 Challenge '99-'02, they listened to the fans and fixed almost every single aspect. Also the cars models were changed and made from scratch to make them more realistic. Track versions were created specifically for each season resembling the real circuits.

With the use of simple text files for track, drivers and cars physics, F1C (as it is now called) turned into a powerful 3D racing platform with the release of free mods from independent developers.
