4. Game Of Thrones
The land of Westoros has already been formatted to the game industries discretion before in the form of an action RPG. Although it allows you to explore several locations, it misses the overall feel of the similar in themes game Skyrim. Many have discussed simply modding Skyrim until it becomes Westoros - the basic mechanics are already in place and it would allow the same exploration of expansive plains with a new storyline and familiar characters. Existing mods don't manage to quite pull it off, and either an official game or communal mod could properly convey the epic proportions necessary to express the Game of Thrones world in a fully interactive, explorable setting.
