Discuss 2d gameplay and how new platforms such as cell phones are taking advantages of this renewed market

2D games are games that are made in the second dimension. These games are can be any type of game from platforms like Mario or adventure games like Terraria.  These games are big in the mobile games market because they are simple due to them only having 2 dimensions. This makes it easy for the players because you either have to use a "joystick" to move the characters like in Terraria or push a button to do a certain action.
