Minimum requirements
To run every game a set of minimum requirements are needed in order to allow the general public to make an informed choice regarding purchasing/downloading/installing your game.
You need to figure out what are the minimum specifications needed to let the game run smoothly so as to avoid getting into the crosshairs of your audience as proposing too low requirements can become a regular scandal if people having purchased/downloaded/installed your game are unable to play it or can only do so with great difficulty.
Here is an example from a real worl minimum requirement list - Tabula Rasa by Richard Garriot so that you can ponder upon what your game asks of your players hardware
