Examples
Super Mario Sunshine lets players controlling Mario explore several "levels" on a tropical island. On some of these one can see quite much of the island, including the areas that make up some of the other levels, but trying to reach them by normal movement reveals invisible barriers in the game world.
The Roleplaying Games that make up the Elder Scrolls and Fallout series strive towards giving players a large game world to explore relatively unhindered except for hostile inhabitants. While the Morrowind takes place on an island and only has the ocean as a barrier to exploration, its sequel Oblivion as well as Fallout 3 and Fallout: New Vegas has to limit the possibility of roaming by introducing barrier that are more or less obviously placed there to limit gameplay rather than to fit the game world.
Games that use computer algorithms to create not only the basic terrain of game worlds but also much of the details in those worlds, e.g. Minecraft, Slaves to Armok II: Dwarf Fortress, and the Elite and Just Cause series, can have such large gameplay areas that players have to spend considerable efforts to be able to either notice the boundaries of the worlds or circumnavigate them.
Using the pattern
Illusion of Open Space is used to make Game Worlds that are or seem (depending on your perspective) larger than the actual space where gameplay takes place. One way of doing this is to model the parts of the Game Worlds which players are not supposed to be able to enter, often proportionally large areas compared to the actual gameplay area, at a lower granularity than the playable area and then hinder players from entering these by having Invisible Walls. This can also be achieved through making them into Inaccessible Areas by having natural barriers, e.g. chasms, strong currents, lava flows, etc., block access to them but this can only be done to a certain extent before they seem like Invisible Walls - and this solution may not work with various forms of Privileged Movement such as flying.
Another way of creating Illusion of Open Space is to use Secondary Interface Screens with maps for choosing Quick Travel. This since the game's interface can show that more of the Game World exists than may actually be able to visit.
Procedurally Generated Game Worlds
Consequences
Illusion of Open Space makes Game Worlds seem larger than they would otherwise. This can help support both Diegetic and Thematic Consistency, the first by not making the Game World presentation end just because the gameplay environment does and the second because many themes imply that there should be open spaces. Diegetic Consistency can be maintained even if the illusion is revealed, but Thematic Consistency is likely to suffer.
