During the 1990s Interactive fiction was mainly written with C-like languages, such as TADS 2 and Inform 6. A number of systems for writing interactive fiction now exist. The most popular remain Inform, TADS, or ADRIFT, but they diverged in their approach to IF-writing during the 2000s, giving today's IF writers an objective choice. By 2006 IFComp, most games were written for Inform, with a strong minority of games for TADS and ADRIFT, followed by a small number of games for other systems.
