AGON

The player takes the role of Professor Samuel Hunt, a cultural historian at the British museum, and explores a 3D pre-rendered environment using a 360° field of view and moving between the various locations and interacting with objects and characters by clicking. In AGON, the cursor will change to indicate what actions players can take, ranging from arrows for movement to a cogwheel for using an object. The player has access to an on-screen dial which can open an inventory and access items; and open files allowing the player to view various documents located in the game. At the end of each episode, except episode 1, the player must face a computer-controlled character in a board game, and win in order to complete that episode. There is a slight discrepancy of the controls between the episodes; for example in Episode 4 the Files section records conversations, whilst documents are stored within the inventory.

All games see Professor Samuel Hunt as the player character, an employee of the British Museum who searches the world for a collection of rare board games for the museum at the beginning of the 20th century. Each episode plays in a different part of the world. While each episode can be played independently, there is an overall plot connecting all episodes.

In 1903, Professor Samuel Hunt receives a mysterious letter and the first page of a Codex. The page makes references to a demonic 'Black King' and to several board games. The letter mentions the Black King is linked to an artifact in the museum. Hunt informs his close friend, Dr Thomas Smythe, about the artifact, and with Smythe's help, locates the artifact in the stores.
