Although it is (in name) the successor to Inform 6, the syntax of the language is entirely different to its predecessor. The link to Inform 6 lies under the hood: an Inform story is translated first to Inform 6, which is then compiled into Glulx or Z-Code by the Inform 6 compiler. This means that works produced using Inform 7 can be played on Z-Code interpreters (although there are some modifications required, as, for example, Inform 7 games tend to use a larger stack than Inform 6).
Inform 7 was first released as a public beta on April 30th, 2006.
Early Inform 7 games
On March 1st, 2006, three example games were released (see the rgif announcement: Three Games in Inform 7). These games were:
- Bronze (Emily Short). Example of pathfinding and room adjacency. This is an updated version of the same game from Speed-IF Gruff.
- Damnatio Memoriae (Emily Short). Example of link-based magic as first seen in Savoir-Faire.
- The Reliques of Tolti-Aph (Graham Nelson). Example of RPG-style combat and magic systems.
Inform 7 was released as a public beta on April 30th, 2006. Three more example games were released at the same time:

- When in Rome 1: Accounting for Taste (Emily Short). Example of directable NPC and an NPC with random characteristics.

All six example games are available from the Complete Examples page.
