Game designers are responsible for designing games on paper. They are responsible for designing the game controls, the gameplay mechanics, weapons, abilities, items, skill trees, gametypes, the different world locations, all the game systems, user interfaces, game menus, multiplayer features, background stories, the lore and so much more.
Before developing a game, game designers generally have to create a High-Level Concept (HLC), a Microsoft PowerPoint presentation, that will help them pitch a new game to the people higher up in the game company. The HLC presents a general idea of what this new game will be about and all its key selling points. It could contain things such as...
Once the game has been approved by the game company internally, game designers can then focus on the creation of game design documents that will become the roadmap for the rest of the team.
Typically, game designers would use a combination of Microsoft Word, Photoshop and Microsoft Excel to create their design documents. However, it doesn't have to be only a Microsoft Word Document. Certain development teams might prefer to build their own wiki, etc.
