a bottom surface;

a first side surface extending from one side of the bottom surface;

a second side surface extending from the other side of the bottom surface;

a first surface extending from the first side surface and opposing the bottom surface; and

a second surface extending from the second side surface and opposing the bottom surface,

the first surface includes a plurality of portions arranged next to each other with spacing therebetween,

the second surface includes a plurality of portions arranged next to each other with spacing therebetween, the game controller comprising:

a controller-side slide member positioned on a side surface of the game controller and configured to slidably engage with the main unit-side slide member, the game controller being configured to be attached to the main unit by sliding the controller-side slide member relative to the main unit-side slide member in a slide direction, wherein

the controller-side slide member includes:

a shaft portion protruding from the side surface of the game controller; and

a top surface portion on one side of the shaft portion that is away from the side surface, the top surface portion being longer than the shaft portion for a direction perpendicular to the slide direction, and

the top surface portion includes a plurality of portions arranged next to each other in the slide direction with spacing therebetween.

11. The game controller according to claim 10 , wherein

at least one of the plurality of portions of the top surface portion is on a slide-direction side relative to a center of the game controller, and

at least another one of the plurality of portions of the top surface portion is on an opposite side from the slide-direction side relative to the center of the game controller.

12. A game system including the game controller and the main unit of claim 10 .

13. A game system including a game controller which is removably attachable to a main unit having a main unit-side slide member and configured to execute a game process,

the game controller comprising:

a controller-side slide member positioned on a first side surface of the game controller and configured to slidably engage with the main unit-side slide member, the game controller being configured to be attached to the main unit by sliding the controller-side slide member relative to the main unit-side slide member; and

at least one terminal on a slide-direction side relative to a center of the controller-side slide member and configured to be electrically connected to the main unit when the game controller is slidably attached to the main unit;

and

the game system further comprising a stop mechanism to resist relative sliding movement between the controller-side slide member and the main unit-side slide member, the stop mechanism including a movable stop member and a recess that aligns with and at least partially receives the stop member when the game controller and the main unit are slidably attached to one another.

14. The game system according to claim 13 , wherein at least one of the stop member and the recess is positioned on the game controller on an opposite side from the slide-direction side relative to the center of the controller-side slide member.

15. The game system according to claim 13 , wherein the stop member is formed as part of the game controller and the recess is formed as part of the main unit, the stop member including a stop surface configured to releasably engage a corresponding surface forming the recess.

16. The game system according to claim 13 , further comprising a release button that is configured to be moved by an operation by a user, wherein

the stop member is movable between a first position and a second position,

the stop member in the first position is more protruding as compared with the stop member in the second position,
