Version 2.3 was bundled with three complete games (Orbit, Zoltar and Bullet Train), and many accessories and utilities (such as sprite and music editors).

Around 2001 François Lionet released via the Clickteam website the source code of STOS BASIC.

AMOS2 replaces STOS and AMOS together, using JavaScript as its code interpreter, making the new development system independent and generally deployed in web browsers.

While giving programmers the ability to rapidly create a game without knowing the internals, STOS was criticised for being slow (especially when intensively using the non-high-level commands), and for not allowing the user to program in a structured manner.

One of the developers in Jawx, Francois Lionet, was later to form Clickteam with Yves Lamoureux and went on to release the Klik (click) series of games-creation tools (which were dissimilar to STOS as they use a primarily mouse-driven interface without the need for traditional code).
