The diversity of media available for smartphones now is huge and almost everything is available with instant gratification becoming a habit that many cannot give up. This means that a smartphone or tablet user can choose whatever they like to entertain them and that they can have the product within minutes.
Now consider that you have some spare time and want something new to keep you entertained. You could rent a film from a producer or starring actors that you like, you could buy the latest album from your favourite band or purchase an eBook by your favourite author. You are then almost guaranteed to be satisfied with your purchase. Or you could take a risk and buy a new game that may or may not be worth the price of entrance.
Mobile games can be addictive, stimulating and pure fun if they are programmed for the mobile environment. Tiny Wings, Angry Birds and Riptide GP are good examples. But many games have been built with ambitious intentions that are too much for the small screen and this can lead to users who buy a lot of games becoming wary about future purchases. Also, you can read an eBook or watch a movie with headphones anywhere. Whether you are waiting at the Doctor’s, waiting for a bus of during a break of only a few minutes. You cannot always do this with games, particularly the ones that require concentration. They also rarely relax you whereas an eBook, music or a film can take you to a new place where you can forget about the normal stresses of life.
Mobile games will always have a place, and will always sell in big numbers, but it is also possible that games in general will have much less impact in our futures that they do now. Media that requires little effort on the part of the user could win out as our lives become more stressful and we have less free time.
