Jane Austen's Estate of Affairs is a hidden-object adventure game where the player takes on a role of Christiana Austen, a niece of Jane Austen, a renowned novelist. The estate is going through some hard times, and Christiana is set to try and find the missing novel of her Aunt that will help with the money problem. But she is not greeted well by the estate's residents or its staff. The game focuses on many aspects of Jane Austen's life featuring excerpts from her famous novels as well as locations from the period such as the Chawton House.
The game is hidden-object in nature, meaning the player traverses various locations and activates hidden-object mini-games by clicking at the glowing areas. Hidden objects are either found by name or shape, and may sometimes require interaction with other objects to reveal the hidden objects that are not visible on the screen at the beginning. Beside the hidden-object gameplay and free movement between locations, the game also features items inventory which can be locked to stay on screen or appear on mouse over near the bottom of the screen. Various objects can either be found lying out in the open or retrieved by completing hidden-object scenes. Very often the player will have to traverse through available locations and collecting objects which in turn will open new ares or locks at other locations and let player retrieve another useful objects which may be the goal or just another key for yet another lock someplace else.
Cut-scenes and dialogues feature full voice-acting with lip-syncing even though character portraits themselves are static 2D artworks. Graphics uses both 3D pre-rendered scenes and 2D graphics art. The game uses unorthodox resolution when played in window mode (somewhere between 800x600 and 1024x768), but in full-screen mode stretches to desktop size resolution in either widescreen mode or keeping its 4:3 aspect ratio with black sides. There are three difficulty game modes available, easy, normal, and hard, which mainly focus on whether the hints are available, how fast they recharge, and if hotspots are more vividly marked on the screen.
