 Så det är obviously lots of lessons to learn from those buckbusters and I was asked to look a little closer into what the success of the game boy. I started to ask all my games av friends and to see what they had to say about it and everyone was just answering in one direct precise word and that was Tetris. So I thought that this might become a very short session then Tetris was included from the very beginning to in the release in 1989 and Nintendo had a long struggle struggle with both the Russian developers and other parts to get the rights for the handheld device for it. So it was obviously a very important key for them and for the release. I was thinking why then Tetris and Game Boy was this perfect match that Nintendo knew of and I started to look at it is kind of strange because other parts were doing very cool stuff at the same time. Much cooler games action games and Tetris is considered and was considered by then to pretty much girl for girls game. So I went to the net and I looked what people had to say about it about the Tetris then and these discussions has been the same for 20 years almost now and this is only half year old. I've heard a rumor that girls tend to like Tetris more than boys do. I like Tetris OK but I'm a girl that likes first person shooters to. I think it's 50 50. I like boys more than Tetris Tetris is still fun. Yes because they like being able to put the long block into the small hole and that's always fun to be a girl in in games forums. Possibly because it's a low action game but I like Tetris as a guy in end. These conversations are always like very confused and they are not leading to any answers. But I turned and I could have a long session in only talking about this genius thing about girls and games because that's my area. Men I went further and found Swedish forums where there are getting a little closer to something. It's easy to start and get into requires concentration but no complicated steering button combinations and the sessions are short. Are you not keeping up at all girls play Sims because they are manipulative and want to control other people. It's easy to get hold of no needs for new console or soapy computer super computers and no downloading to get the game. And here they are very close to into something that has to both Tetris and Game Boy to do. But first we'll have a look at the competition before we do any conclusions. These are all other branded consoles both earlier and later than than the Game Boy. The links in the middle is the Atari console handheld device released right after the Game Boy. This had much cooler processors for much cooler games but was still not at all the same success. All of these have focused on high graphics and fun action games mostly and where you know provided with a high technology of the time then that is targeting hardcore gamers of course. Hardcore gamers are mainly boys about 16 30 years old. That is about 10 percent of the population. And if we look at the Nintendo devices I've urged for each and every one of these and I've owned everyone too. And it's clearly to me at least that Nintendo had some sort of idea of that the potential market of gamers were much more bigger than those 10 percent. So what they did is they made it they created a toy instead of a gaming console a toy that where they wanted everyone to be able to possess one and able to play and start to play easily. So they prioritized a few things that that at the time no one else did they prioritize long life time battery for example. And with that long life time battery it's important. This is kind of like circle circle arguments to make something portable and important you know like be able to put something in your bag and bring it to the school yard and let anyone else play with it. You have to have long life battery times lifetime. So what they did is that they didn't prioritize beautiful graphics and they didn't prioritize great strong processors which man also made a lower cost a lower cost for everyone to be able to buy. They also prioritize simple interaction for everyone. We know preschools to be able to just pick it up and start playing. So what they did is maybe a recipe probably very important for many gaming actors today to they made casual games as casual as ever possible for casual people.
